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 + 15x2 - 16
A. -4, 4; f(x) = (x - 4)(x + 4)(x2 + 1)
B. -1, 1; f(x) = (x - 1)(x + 1)(x2 + 16)
C. 1; f(x) = (x - 1)2(x2 + 16)
D. -1, -4, 1, 4; f(x) = (x - 1)(x + 1)(x - 4)(x + 4)
