Use the Rational Zeros Theorem to find all the real zeros of the polynomial function. Use the zeros to factor f over the real numbers. f(x) = x3 + 2x2 - 9x - 18
A. -3, -2, 3; f(x) = (x + 3)(x + 2)(x - 3)
B. -2; f(x) = (x + 2)(x2 + x - 9)
C. -3, 2, 3; f(x) = (x + 3)(x - 2)(x - 3)
D. -3; f(x) = (x + 3)(x2 - x - 6)
