Use synthetic division to divide f(x) by x - k for the given value of k. Then express f(x) in the form 
for the given value of k.f(x) = 2x5 - x4 + 3x2 - x + 5; k = 1
A. f(x) = (x - 1)(2x4 + x3 + x2 + 4x + 3) + 8 B. f(x) = (x - 1)(2x4 + x3 + 4x2 + 3x) + 8 C. f(x) = (x - 1)(2x4 - 3x3 - x) + 6 D. f(x) = (x - 1)(2x4 + x3 - x2 + 2x + 1) + 6
