@GodGirl360  can you help me with this one too please? :)

I would say D, but be careful. I'm going through this in algebra right now and haven't gotten that far.

@Anonymous1321 can you help me? :)

@wio what about you? :)

anonymous · Answer

i think step 2 because where did the -9 come from when there is only + numbers

anonymous · Answer

D is not the answer!! See how he factored the polynomial and had 2 plus signs, then all of a sudden had one plus and one negative sign?

Thanks guys! b is the answer! :)
