Question

Given a polynomial f(x), if (x + 7) is a factor, what else must be true? Help plzzz im running out of time

Answer 1

Answer: f(-7) = 0
For the factored form of f(x), if x = -7, then one of the factors will be equal to 0, since (-7 + 7) = 0. This will cause the entire y-value to be 0, because anything multiplied by 0 = 0.
