Let $H(x) = 3x^4 + 6x^3 - 2x^2 + 1$ and $g(x)$ be a linear polynomial. If $\frac{H(x)}{(x-1)(x+1)(x-2)} = f(x) + \frac{g(x)}{(x-1)(x+1)(x-2)}$,then $H(-1) + 2H(2) - 3H(1) =$

  • A
    $f(-1) + 2f(2) - 3f(1)$
  • B
    $H(-1) + f(2) + g(3)$
  • C
    $g(-1) + 2g(2) - 3g(1)$
  • D
    $H(1) + 2f(2) - g(1)$
