  • math sucks

  • Thank you, I was confused when I got to last part, before i seen the video, but know I know there suppose to be a reminder.

  • great video! Steps are mapped out very nicely.

  • If I was presented with that I'd probably walk away

  • You look scary

  • @Dman761 he was already dead

  • At 4:08, when you look at x^3+4x^2+16x^2+61+(249/x-4) ....I Believe that the Currect Way Should Show x^3+4x^2+16x+61+(249/x-4)

  • *Correction

    It's about 4:02 where the 16x^2 should just be 16x

  • a video with a power of 2 in the denominator would be really helpful and as for the comment above that it has to be just x and a number is wrong it is divisible if the power of the numerator is greater than the power of the denominator

  • you're awesome!

  • Thank you so much! I may pass my test now! lol

  • Thank you so much!

  • thanks for the info even though i did not understand the discussion on the video, i understood how the answer was taken

  • when can't we use synthetic division method?

  • Comment removed

  • You can't use it if there's something higher than x, such as x^2 or x^3. Basically u can only use it when it has an x and a number.

  • Thanks for the help. Can you send me the tutorial on factoring please.

  • thanks!

  • oops my bad, ignore watever i just said.

  • Comment removed

  • yeah!.. he made a mistake

    instead of X^3+4x^2+16X+61+249/X-4

    his anwer is X^3+6x^2+16X^2+61+249/X-4

  • yap you are right. a little mistake in making of equation.

  • That's not a 6 idiot. It is a 4. You can tell by the strokes. Duh.

  • instead of x-4 can u use x+4 plz answer need help

  • x-4=0

    then x=4

    ok

  • Very helpful but yeah, he made a slight mistake, the answer should be X^3+4x^2+16X+61+249/(X-4)

    He already acknowledged this in an earlier comment on the video. The correct answer is X^3+4x^2+16X+61+249/(X-4)

  • Hello,

    This was a great video. Thank you.

    Please mail the complete tutorial.

    Thanks.

  • thank you!! you made me pass my first quiz in college.. could you be my tutor maybe just here in youtube..? or can i have your email adress for future purposes. im kindof bad in algebra. it would be super if you show me some more formula's! take care!

  • thanks for the help, but isnt the answer x^3-4x^2+16x+61+249/(x-4)?

  • beanboy5555, you are correct. The 16x in you answer is the way to go. The answer should not have 16x squared.

  • You are the people who make maths tough fr children... better use remainder theorem and cut steps shorter,.. put 5 in place of x in whole of theeqn. and get the answers instantly...

  • thank you very much!

  • thanks! you're cool!

  • You're awesome. I was doing Natural Logarithmic Integration and forgot how to divide polynomials. Two seconds of Google later and I run into this amazingly straightforward video. Thanks for the refresher.

  • I have a test on this today and I was freaking out. Now I feel so much better. I wish you were MY teacher.... well, I guess you are now.

  • Hello and thanks for taking time to post this video for the benefit of others. I, for one, am highly appreciative! Can you send me the tutorial to this lesson and factoring? Thanks

  • Hello, I have a question, since in the original problem, x^4 is the highest exponent, what happends to the x^4, when your answer is x^3+4x^2+16x+61+249/(x-4), where does the x^4 go?

  • it was the one (x) term in (x-4); the highest power of the divisor is 1, so you the quotient will be of an order 1 less than the original number. (x^4 + etc....)

  • thank you you have saved my homework efforts my math teacher will love to see this video

  • thanks this helps

  • thank you for the fantastic tutorial! jus one mistake, *16x

  • thank you very much. this will certainly help on my midterm tomorrow.

  • Thank you so much, this clears up all of my questions!!!!

    You're a life saver!

  • thank you so much!!

  • i have some brain storming here while watching your video and that is what if the divisor is not given how could i come out with the answer.

    and what if the given diversor would be 2x-3

    how could i work on it?

  • hey im just supposing, but if 249 was divisible by 4, do i have to divide and leave the x below?

  • Thanks. I was having a small amount of trouble with synthetic division. The small error at the end doesn't really matter.

  • i don't understand how the answer came out with two x^2 s

  • You are right. My answer in the video is wrong. It should have been X^3+4x^2+16X+61+249/(x-4)

  • You are right. My answer in the video is wrong. It should have been X^3+4x^2+16X+61+249/(x-4)

  • thats wrong the answer at the end should be x^3-4x^2+16x+61+ (249/x-4)

  • omg face

  • How can I determine if x-a is a factor or x^3-a^3. I know how to use synthetic division but I am confused how to set it up and how it works when you are dividing by a.

    Can you help?

  • thanks this really helped me alot (:

  • thankssss

  • Can you ALWAYS use the synthetic division to divide polynomials?

  • As long as you are dividing by a binomial with a degree of 1.

  • Amazing system. i am taking College pre-Algebra and this poly-nomial thing was throwing me for a loop. This Really helped thank you very much. Now what about factoring nad factoring by grouping? :)

    Thnks Stephen

  • class act, now aren't you proud of yourself?

  • You need to keep your little wise comments to your friends. Why are you looking at algebra anyway? We ALL can tell by your comment you're not smart enough to even do regular division!! He is on here tring to help people, and you are making KOREA look even worse!!!

  • my last comment was meant for srleeplus3377

  • You made an error in the final answer. You have two x squared terms. One of those should just be an x. :)

  • hey professor,

    I made up my own problem and tried to solve it, can you check my answer for me please? (there might be something wrong that I did since I'm in grade 10 and haven't done this in school yet.)

    here is the problem: 15x^5 + 12x -2/x - 30

    my answer:

    3(5x^4 + 150x^3 + 4500x^2 + 135000x + 4050004) + 364500358/x-30

    If it is wrong i will show you my work to see where i went wrong but at the moment it is too much of a hassle to type it on youtube.

    thnx

  • hi im just wondering what grade (11,12, post secondary) level these synthetic operations are. I just finished grade 10 and i am trying to get ahead for next year

  • I'm a sophomore. That's what we're studying in Algebra right now.

  • Very helpful. I'm taking a Calculus upgrade and this is extremely helpful. Thank you.

  • thanks i suck at algebra this helped me alot ^^

  • wouldn't you add the x squared things to get 20 x squared?

  • I am glad that you asked this question. There is a mistake in the answer. It is really 4x^2 + 16x so you can not add

  • i still didnt got how its x^2 to the 4 and x^2 for 16 also...

  • it is incorrect see above. My mistake . It should have been 4x^2 + 16x and not 4x^2+16x^2

  • right. thank you professor.

  • Thank you professor!

  • lolz at 0:001

  • thank you! The video really helped me!

  • thanks alot really! ive been sick from school and my friends just gave me my mathbook and im staring at it blankly not knowing what to do.. haha now i can actually do my math homework

  • I need to get a textbook...my brain just feels like a brick...

  • how will you transpose a polynomial divisor?????

  • how do you get X^3

  • Thank you, thank you, thank you! Your presentation was the best and most consise lecture I have ever studied! Thank you, Jai Shree Krishna, Namaste, Greetings!

  • excellent presentation, thanks

  • Thanks for doing this!

  • The math is important because

    the math teach you how to solve a problem

    in Times Minus Or Division

  • Hello Mathproblems!!

    I dont really understand what had happened with the polynomial......im learning algebra and im in 8th grade and for some reason i dont get how division of polynomial is solved......can you help me out and explain more about how like all the steps are.....the way you said them in this vid for me is hard to understand. =]

  • Hey mathrpoblems,

    Your final answer seems incorrect. If you multiply your quotient times the divisor, you don't get anywhere near the original polynomial that you were dividing. I went and did the problem using long division and got: x^3 + 4x^2 + 16x + 61 + 249/(x-4)

    If you multiply my answer times (x-4) you get x^4 - 3x + 5

    Thanks, take care.

  • that is what I have

  • Uhh no, at 3:38 I'm seeing that you have, x^3 + 4x^2 + 16x^2 + 61 + (249)/(x-4). The difference being I have 16x where as you have 16x^2.

    If you simplified your answer it would read:

    x^3 + 20x^2 + 61 + (249)/(x-4). And this is incorrect.

  • you are correct I meant 16x and not 16x^2

    It was an error

    Thanks for pointing it out

  • That was really helpful. Thanks for sharing!

  • No problem.

    Are you a high school 12th grade student?

  • No. I am already in college but I need some refreshing on my math skills because I haven't had a math subject in a while. I am preparing for next semester using your videos.

  • That was really cool.

  • Thanks

  • well do you think you could do a video on velocity vs. time graphs. i understand the graph itself but i don't understand it at an intermediate or hard level. let's say an object accelerates constant increasing velocity, then slows down, and completely stops. how would you graph that. if you want, in the video, show me how to graph that situation and any other type of situation you want to make up. i have a test tommorow over these type of graphs and need as much help as possible.

  • Please watch my video specially made for you only

    Good Luck on your test tomorrow

  • IT is similar to Multiplying Polynomials just different I Really Appreciate It Thank you For Helping Me Out with my Question I'm more enlightened on the certain tricky equations and topic of Polynomials its was just dividing that got me a little screwy! HAIL Vinod MATHMATICAL MASTER OF THE arithmetic ARTS!!!

  • No problem anytime if yopu need halp just shout

  • hehe, you don't need to thank us, it's us thanking you. I find the videos very entertaining when I get the time to watch.
