A computer? If the first coefficient is negative, the answer I gave you is right.

anonymous · Answer

my homework is website called Course Compass and I wrote the answer extacly how you put it in here and it told me it was wrong

anonymous · Answer

I don't know what to do, then. If you don't believe my answer, use foil to expand it. Maybe the site wants you to factor the negative out and/or switch the factors?

anonymous · Answer

I believe you that is the answer........ I just don't know how they want it written

anonymous · Answer

Just keep on trying...who knows, maybe the site's misbehaving?

anonymous · Answer

I'm doing a different one right now........... -16t^2+48t+160.... it's exactly like the last one

anonymous · Answer

use 80 and 2 as your factor of 160
