Greg and Joan are trying to figure out which polynomials from the list below have (x - 3) as a factor? Greg believed that only A and C had a factor of (x - 3) while Joan agreed with Greg but also thought D was correct as well. Who is correct? Use the remainder theorem and factor theorem to help you show who is correct AND to explain why. (A) A(x) = x3 - 2x2 - 4x + 3
(B) B(x) = x3 +3 - 2x - 6
(C) C(x) = x+ - 2x3 - 27
(D) D(x) = x4 - 20x - 21
