You should probably post this as a new thread :-) I'll help you though, just tag me

Answer 11

So the two factors should have a sum of 5, and a product of -14. What are two numbers that give us this? It's (+7 and -2)! Remember when we factor them the signs are the opposite. So the answer would be (x+7)(x-5)
