Quizplus · Accepted Answer

This is a quadratic trinomial in two variables, so we want to look for two binomials that have a first term that multiplies to x^2, a last term that multiplies to 5y^2, and a middle term that adds to 7xy. The only option that works is (x + 7y)(x + 5y), so the answer is C.
