Question

Solve each equation by factoring.
17) 2x^2-7x-15=0
I don't know the factors can someone help me? What goes into -15 but adds up to -7?

Answer 1

Hello, I understand why you did -15 but you are meant to multiply the numbers under the arrow. This may seem very confusing but I’m sure with practice you will get used to these types of questions, thanks.
