by the factor theorem what can be said about the polynomial function s(x) if s(-5)=-4

Question

A. s(x) has no real zeros

B. x+5 is a factor of s(x)

C. s(x) has five real zeros

D. x+5 is not a factor of s(x)

Answer 1

The factor theorem tells you that a polynomial has a factor only when . So if s(-5) is not 0, we can draw the conclusion that (x+5) is not a factor of s(x).
