Use Descartes' Rule of Signs and 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) = 5x4 - 9x3 + 14x2 - 18x + 8
A. -2, -1, 1, - 
; f(x) = (x - 1)(5x + 4)(x + 1)(x + 2)
B. 2, 
; f(x) = (x - 2)(5x - 4)(x2 + 1)
C. 1, 
; f(x) = (x - 1)(5x - 4)(x2 + 2)
D. -2, -1, 1, 
; f(x) = (x - 1)(5x - 4)(x + 1)(x + 2)
