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) = 3x4 - 2x3 - 10x2 + 15; k = 2
A. f(x) = (x -2)(3x3 - 4x2 - 2x - 4) + 7 B. f(x) = (x -2)(3x3 + 4x2 - 2x - 4) + 7 C. f(x) = (x -2)(3x3 + 4x2 - 2x + 11) + 22 D. f(x) = (x -2)(3x3 + 4x2 + 2x + 4) + 22
