Wow - How bad is the American Education system?! I'm 14 and understand this completely (No, I'm not Asian. I'm British). Catch up.
Anyway, this isn't the way I would have done it, but it works.
(-)4 and (-)1 are the only factors in 4 which would add to make -5, which is were he got the (x-4) and (x-1) from. We know that anything multiplied by 0 is equal to 0, one of the brackets must equal 0.
@OliviaSBee How dumb are you is the real question. It makes real sense to judge the entire american education system on a few comments from a youtube video. Smart ass.
@Baseballbat95 For your information, I'm not just basing it of 'a few comments from a youtube video'. I actually lived in America for over a year and I found both the schools I attended to be pretty crappy compared to most others I've been to (including one in a developing country).
Also - what is with the overly-defensive comment? I'm confused at why you feel the need to argue with a teenage girl on the internet about something like this.
where the fuck did the third line come from?? where the fuck did (x-4)(x-1) come from? no fucking idea, just skip the explanation just like every damn math teacher would -.-
@nerokyia after hes done factoring the original equation he gets (x^2 -5x +4). (x-4) x (x-1) is a factored version of (x^2 -5x +4). (x-4) x (x-1) = (x^2 -5x +4)
@nerokyia Okay, here's another way to do it. As you see 3(x^2 -5x +4), find out what 2 numbers multiply to 4 and add to -5, the only numbers possible to do that are 1 and 4, however since -5x is a negative, both numbers must be a negative. From doing it like this, you can easily see how he got (x-1) and (x-4) right?
@AvatarRoku1 the (x-4)(x-1) come from numbers that factor into the second line 3(x^2 -5x +4) Just always remind yourself that these numbers are the simpler version of the second line, it helps you understand it a bit more better.
Do you know how to FOIL? Look it up. If you multiply the third line together, you'll get the second line, so the third line is really just a simplified (factored) version of the second.
@rhbecky Its one of the sets of factors you can make to get 4, like 4x1, 2x2. However you need a set that'll add up to -5x. You get -1x-4 because if you add -1+-4, you'll get -5! (the -5x) Hope this helps :)sorry if its confusing
...also a good intro to the "Zero Product Property" (e.g., the "3=0" expression, illustrating the futility of an arbitrary constant multiplied by the expressions containing "x". In other words, that poor "3" could just as well have been a "9" or a "211" or 66 2/3" or anything at all...
@deathklok29 because 1x4 is 4, for that last number 4 and you have 1 + 4 equals 5, the middle number, you cant use 2x2 because 2 + 2 =4, it has to equal the middle number (5) does that make sense? lol
Check out "Quadratic Equation Solver!" on Android Market. It gives answers in exact form and is a great way to check your work. Here's the link (or search 'scapelitte' on Android, then select 'Quadratic Equation Solver!'):
He actually didn't do a good job of telling us WHY he used -4 and -1 that could have been useful to many people. so let me tell you.... He used -4 and -1 because you want the sum of -5 and product of 4. Therefore -4 + -1 = -5 and -4 * -1 = 4. and also he brought down the 2brackets in step 3 because there is an X^2 so that means two terms, and the -4 and -1 are also called NPV's (Non-permissable-Values) which is what "X" cannot equal.
yooo i got 2 ditmas is62 im in 7th grade insitute APVA we go to talentlike keyboard im in keboard there also bad they suck!! then there art... their art isent bad thoe there dance 2 they rock da house yoo now they made new talent but ima stop there my math techer is mr.k hea neva told us his real name cuz itz ODEE hard lmao no joke ok biee
Okay so...this is a really easy problem but I hate how he doesn't explain what he does. I'm trying to find a good video to help me teach this stuff to my sister, but he doesn't explain any of the steps of factoring. He just does it and expects you to follow along! Grrr...
@SubliminalGenocide18 The 5 was factored by the -4 and the -1 meaning, -4 + (-1)= -5.. he got -4 and -1 because you have to find 2 numbers that you can multiply to get one number ie -4 x -1 = 4 and those same two numbers have to add up to the other number ie -4 + -1=-5.. Its the way my professor taught me and its a little easier to remember.. so in conclusion the -4 and -1 has to add up to one of the numbers, -5, and also be multiplied together to get the other number 4..

this needed to got in detail, usuallyu these videos are perfect examples for everyone. This video was only for the advanced. It would be nice if there were more videos made on factoring polynomials in detail and step by step. Thanks for sharing ;D
this is great but what about factoring with larger numbers? what do you do with something like 6n^2 + 18 -24=0 I just don't understand the process in what you put in the brackets : 6(n-?)(n+?) = 0 do you use FOIL or what? I hate math
@9578755 you have to factor 4 which will equal to your middle term which is -5, that case factoring 4 will be 4X1=4... Then again, how do you know how they got (x-4)(x-1)? to get -5x in the middle, you have to add -4+-1=-5
I recommend this excellent Math channel: ( Mathmatchpoint ) to everyone who wants to become good at Math. He is going to teach you Math the EASY WAY, from the basic to the advanced topics. The great thing is that his videos are categorized within playlists. It is easy to know which video to watch next. This was the least I could do for him (let others know about his videos). Thanks to him, I got 97% on my Math test.
When someone attractive asks you how to do this type of question, use your math skills to impress them! That's one way to apply it in real life! Plus, when you're helping someone else learn, you are testing your knowledge and helping yourself study as you recall the method that you used to get to the solution. Math isn't so much about how we can apply it to real life situations, it's about the method(s) that we used to get to that solution. By understanding math we become better problem solvers.

@9578755 you have to factor 4 which will equal to your middle term which is -5, that case factoring 4 will be 4X1=4... Then again, how do you know how they got (x-4)(x-1)? to get -5x in the middle, you have to add -4+-1=-5

@k1ssj0y16 forgot to put negatives on 4X1..... multiplying two negatives will equal to a positive.....

Quick question. If you cannot pull out a GCF, what do you do after? 4x^2-7x-15=0 is the question.

I recommend this excellent Math channel: ( Mathmatchpoint ) to everyone who wants to become good at Math. He is going to teach you Math the EASY WAY, from the basic to the advanced topics. The great thing is that his videos are categorized within playlists. It is easy to know which video to watch next. This was the least I could do for him (let others know about his videos). Thanks to him, I got 97% on my Math test.
Go to his channel: Mathmatchpoint
Math will become easy to understand and do

What's the difference between solving a polynomial and factoring it?

When someone attractive asks you how to do this type of question, use your math skills to impress them! That's one way to apply it in real life! Plus, when you're helping someone else learn, you are testing your knowledge and helping yourself study as you recall the method that you used to get to the solution. Math isn't so much about how we can apply it to real life situations, it's about the method(s) that we used to get to that solution. By understanding math we become better problem solvers.
