Answer 12

So if you have to equal -36, and make sure the two factors equal -5, which factor out of 4 and 9 will be negative?

Answer 13

if you add -4 +9 that equals 5. Try again.

Answer 14

Ok, so then you just place 4 and -9 in one of those parentheses we set up.
Can you show me how that will look?
