I am asked to factor the equation To my knowledge, your supposed to find pairs of factors that multiply to give -15 and add to give -4, correct? I can't find a pair that gives both those answers. I'm stuck.

Thanks, looks like the answer is and I would like to ask one more thing. what is the reasoning behind the factors not actually adding up to -4, yet still being the correct answer?
