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) = x4 - 9x2 - 400
A. 5; f(x) = (x - 5)2(x2 + 16)
B. -5, -4, 5, 4; f(x) = (x - 5)(x + 5)(x - 4)(x + 4)
C. -4, 4; f(x) = (x - 4)(x + 4)(x2 + 25)
D. -5, 5; f(x) = (x - 5)(x + 5)(x2 + 16)
