The function f(x) = ax 3 + 4x 2 + bx 2, where a and b

Question:

The function f(x) = ax³ + 4x² + bx – 2, where a and b are constants, is such that 2x – 1 is a factor. Given that the remainder when f(x) is divided by x – 2 is twice the remainder when f(x) is divided by x + 1, find the value of a and of b.
