Q4 Single Correct Medium
Let $$f : R \rightarrow R$$ be a function as $$f(x) = (x - 1)(x + 2)(x - 3)(x - 6) - 100$$. If $$g(x)$$ is a polynomial of degree $$\leq 3$$ such that $$\displaystyle \int \frac{g(x)}{f(x)} dx$$ does not contain any logarithm function and $$g(-2) = 10$$. Then

$$\displaystyle \int \frac{g(x)}{f(x)} dx$$, equals
  • A. $$\tan^{-1} \left ( \frac{x - 1}{1}
    \right ) + c$$
  • B. $$\tan^{-1} (x) + c$$
  • C. None of these
  • D. $$\tan^{-1} \left ( \frac{x - 2}{2}
    \right ) + c$$
