Algebra II - 3.3 Factoring Polynomials

[RyeinGoddard]

Your a good teacher.

[30888316413]

wow I can't believe I understood any of that.

When I clicked on this video I was worried your name was an oxymoron(I'm glad I was wrong)

this video taught me more in 10 minutes, than I learn in an entire week of grade 11 math class with my teacher. I look forward to seeing the rest of you're videos.

[gotulogotulo]

Excellent video. Thank You.

[monjensid]

Wow! Thank you.. before watching this great video, i dont have any idea how this FACTORING thing works.. Thank you..

2:13 I can't understand why you got 6x and 3 as the exponent.

[TheCoolMathGuy]

@heyyou417 @heyyou417 We're looking at the numbers and letters (variables) separately.

6 is the largest common factor of 6, 30, and 12.

x^3 (x with an exponent 3) is the common factor for x^5, x^4, and x^3.

So you end up with 6 and x^3, or 6x^3.

@TheCoolMathGuy Thank you.

can u solve x^2+7x=0

a quadratic equation

I'm in the 11th grade. I have been in 3 different schools in the past 3 years. I have NEVER understood math and have always gotten an F because i find it hard to focus. So today, i decided to start over and stop slacking and focus and thanks to you i was able to ace my math assignment for the first time in YEARS. I am sooooooo excited & I feel incredibly proud of myself . I also think i might actually enjoy math =D thank you sooo much!

[TheCoolMathGuy]

@CheoitzAza Absolutely thrilled to hear it! Thrilled.

Excellent, understandable presentation. Thank you! I'm in college now, after 20 years away, and dusting off the dust and rust. :) Doing good so far, but I get stuck on occassion when factoring polynomials. I still question myself as to whether something can be factored even further. Some of the examples presented left me wondering if they could be further factored. I'll be a master eventually, witth your added help!

[TheCoolMathGuy]

@jdSLider5 If you have questions about specific examples, go ahead and post it. We'll see what we can do.

[ShaxAMV]

Amazing, was trying forever but this video finally made me get it. Thanks a lot.

[SophiaMaria023]

do you have to take out the power if they're in common? because when my teacher did it, she didn't do that. maybe she made a mistake on that example but idk....

[TheCoolMathGuy]

@SophiaMaria023 You have to be more specific with your question. Do you mean when you are dealing with the same exponent across the board?

[perrygreek]

This is the first time I understand factoring! Thank you very much!

[badrison]

You sir are an awesome teacher. This explanation helped a lot. Thank you so much

[Harrysun5134]

ok if you were my math teacher id be acing math no doubt....the 1 I have now is awful THANK YOU!

[TheCoolMathGuy]

@Harrysun5134 If you need individual lessons, get them on the Cool Math Guy site. Look in the "Free Math Help" section first to see if your topic is there! Don't let a clumsy math teacher keep you from learning math!

[didi5515]

i had an algebra final today and im pretty sure i only got the questions bout these polynomials right:D thanks!!

[asdrenn32]

Awesome teacher thanks a lot sir!

[TheCoolMathGuy]

@asdrenn32 We're glad to help.

[SimritSingh101]

O...M...G.. thankyou! My calc teacher thought she could give us a bad grade by giving us a pop worksheet worth a lot of points.. she doesent know i have resources B-)

[biolexyable]

thanks brah 

[mollymollyspazin]

Thank you so much! You made this easy... I appriciate you right meow! It wasnt taught to me last quarter and I need it now. Im taking all online classes... MY MISTAKE!

[TheCoolMathGuy]

@mollymollyspazin Hey, at least you knew where to find good resources, good for mew.

[himynameiseugene1234]

thanks a lot sir

[TheCoolMathGuy]

@himynameiseugene1234 Anytime.

[ittssnikki]

I'm honestly crying right now! Thank you so so so so soooo much! :')

[TheCoolMathGuy]

@ittssnikki :)

[CNoMoreNoobz]

hey all newbies, my teacher in grade 5 this is hard. But I really have to admit it she lied, its pretty easy

[TheCoolMathGuy]

@CNoMoreNoobz If a teacher tells you something is going to be hard, chances are, that's what makes it hard! At least you figured that out.

[CNoMoreNoobz]

@CNoMoreNoobz When a cool math teacher as him, nothing is hard. I would really write an essay about him, he is really true inspiration!

[goblinob]

@CNoMoreNoobz Maybe you should work on some proper sentences before jumping into essays.....

Nice video

[TheCoolMathGuy]

@Oranges961 There is no "main" reason. The technique of factoring is a thread that runs through the fabric of almost every math course that follows Algebra I. If I were to try to list every instance where factoring is involved in Algebra II, College Algebra, Trigonometry, Calculus, Differential Equations, Linear Algebra, and on and on, it would require all afternoon. The situations listed are just the beginning of that long list.

[omgwtfbbqlmaorofl]

wow u provided a lot of examples thanx! i think im ready for my test tomorrow

[klevdav]

He really iz a kewl math guy

[TheCoolMathGuy]

@klevdav :)

[efialo]

Thank you. You explain yourself well, I'm still not getting this stuff, but I will.

[TheCoolMathGuy]

@efialo If you have specific questions about the areas you are having difficulty with, you can go to the Contact Us page on the CoolMathGuy (link in the description above) and ask. Good luck!
