Given the polynomial function f(x), find the rational zeros, then the other zeros (that is, solve the equation ), and factor f(x) into linear factors.f(x) = x3 - 6x2 + 13x - 20

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