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) = 2x4 - 16x3 + 33x2 - 8x + 16
A. -4, 4; f(x) = (x - 4)(x + 4)(2x2 + 1)
B. 4, multiplicity 2; f(x) = (x - 4)2(2x2 + 1)
C. no real roots; f(x) = (x2 + 16)(2x2 + 1)
D. -4, multiplicity 2; f(x) = (x + 4)2(2x2 + 1)
