So the problem says to solve by factoring.
X^2 - 12 x + 32 = 0
Normally you would move everything to the left. In this case that's already done. So if I understand it correctly I have a trinomial equation with two variables at this point.
So I need to have to have two terms since there are two different unknown factors. So then I find factors of 32: 16, 8, 4, 2.
My question is why out of those factors do I use -4 and -8? Is it simply because when combined they equal -12x?
