Question

Given the polynomial f(x), if (x+5) is a factor, what else must be true?

Answer 1

-5 is a root

Explanation:

It would help to see any possible answers for this if this is a multiple choice question, but if a factor of f(x) is (x+5), then -5 must be a root of a function.

To find roots, set factor equal to zero and solve:

x + 5 = 0

x = -5
