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 - 27x - 54
A. -3, multiplicity 2; -6; f(x) = 
(x + 6)
B. -3, multiplicity 2; 6; f(x) = 
(x - 6)
C. -6, -3, 3; f(x) = (x + 6)(x + 3)(x - 3)
D. -3, 3, 6; f(x) = (x + 3)(x - 3)(x - 6)
