Question

I have no idea what I'm doing here.

Answer 1

I started simplifying and such, but the entire thing turned to crap and I'm really frustrated, because I've been on this lesson for a week now and the instruction videos aren't helping.

Answer 2

HINT: \[x ^{2} + x - 12 = x ^{2} + 4x - 3x - 12\]

Answer 3

\[x ^{2} - x - 20 = x ^{2} - 5x + 4x - 20\]

Answer 4

\[3x ^{2} - 24x + 45 = 3(x ^{2} - 3x - 5x + 15)\]

Answer 5

\[12x ^{2} - 48x - 60 = 12(x ^{2} - 5x + x - 5)\]

Answer 6

Now just factor and simplify

Answer 7

I'm really confused. How did 3x^2 - 24x + 45 turn out to x^2+4x−3x−12?

Answer 8

I think you are misreading what I wrote

Answer 9

I essentially broke down all the terms in a way which is easy to factor

Answer 10

Answer 11

I understand what you were trying to do now xD
@Luis_Rivera I got those exact factors, I just didn't know that 3 could be separated from 3(x-3). Thanks for clearing that up for me!
