Question

I'm having a hard time factoring this trinomial.
16r^2-16r-12
I can't seem to find a factor of -12 that adds up to -16?

Answer 1

Maybe factor out the 4, first, see if that simplifies things?

Answer 2

4(4r² - 4r - 3)

Answer 3

Good idea, thanks! I forgot I could lol.

Answer 4

I still don't know where to go with this, but you seem to :D

Answer 5

I have the answers, I was just trying to figure out how the problem was done. But there are three different answers: 4(2r-3)(2r+1) or (8r-12)(2r+1) or (8r+4)(2r-3) if that helps :)

Answer 6

They're basically the same, no? Just deciding where to distribute the 4, or to distribute it at all :D
