@nincompoop please help, I'll fan & medal you (:

you and your ways -_-

What's going on?
Factoring stuff and simplify again?

Oh it's one of these types :O

Uh-oh, that doesnt sound good ;(

|dw:1440828539698:dw|Have you learned this goofy method before?

Not at all!?

Ehhh scratch that, let's do factor by GROUPING instead :)
That's a better approach anyway.

Ohh I know how to do that ;p But I thought you needed 4 terms?

So what you're doing is, splitting the middle term in some clever way so you can have nice groups.

\[\large\rm 5x^2\color{orangered}{-8x}+3\]

Okay, then I haven't done this before haha. Uhmm I really have no idea :/

We'll multiply A and C, giving us 15.
Factors of 15 that add to -8?
Hmm

15*1 = 15
15 + 1 = 16
Hmm those didn't work

5 and 3

5 * 3 = 15
5 + 3 = 8
Hmm it didn't give us -8 though D:

;( I have no clue how to get -8 from the factors of 15..

Oh!!! Lol why do I always miss this?? -5 and -3! lol

Ok good.
So that's telling us that we want to rewrite -8x as -5x and -3x.

\[\large\rm 5x^2\color{orangered}{-8x}+3\]\[\large\rm 5x^2\color{orangered}{-5x-3x}+3\]

Ohh okay I remember this! And the groups are (5x^2 - 5x) and (-3x +3)

(5x^2-5x) + (-3x+3)
k good :) now factor it out

Oh, sorry! So I got 5(x^2 - x) + 3(-x +1)

MOAR :O
moar stuff

What do you mean?

Oh! Okay so it's 5x(x-1) + 3(-x+1)

5x(x-1) + -3(x+1) lol (:

Hint Hint, I color-coded the thing we're pulling out :3

Lol so we just get 5x-3 (:

Yayyyy! I solved it (: I got 4/x-11 thank you bunches

yay \c:/
