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 - 4x2 + 9x - 10
A. 2, 1 + 
, 1 - 
; f(x) = (x - 2)(x - 1 - 
)(x - 1 +
)
B. -2, 1 + 2i, 1 - 2i; f(x) = (x + 2)(x - 1 - 2i)(x - 1 + 2i)
C. 2, 1 + 2i, 1 - 2i; f(x) = (x - 2)(x - 1 - 2i)(x - 1 + 2i)
D. 2, -1 + 2i, -1 - 2i; f(x) = (x - 2)(x + 1 - 2i)(x + 1 + 2i)
