समाकल का मूल्यांकन करें: $\int \frac{x^2 \, dx}{(x^2 + 2)(x^2 + 5)}$

  • A
    $-\left( \frac{\sqrt{2}}{3} \tan^{-1} \frac{x}{\sqrt{2}} + \frac{\sqrt{5}}{3} \tan^{-1} \frac{x}{\sqrt{5}} \right) + c$
  • B
    $\left( \frac{\sqrt{2}}{3} \tan^{-1} \frac{x}{\sqrt{2}} + \frac{\sqrt{5}}{3} \tan^{-1} \frac{x}{\sqrt{5}} \right) + c$
  • C
    $\frac{\sqrt{2}}{3} \tan^{-1} \left( \frac{x}{\sqrt{2}} \right) - \frac{\sqrt{5}}{3} \tan^{-1} \left( \frac{x}{\sqrt{5}} \right) + c$
  • D
    $-\frac{\sqrt{2}}{3} \tan^{-1} \left( \frac{x}{\sqrt{2}} \right) + \frac{\sqrt{5}}{3} \tan^{-1} \left( \frac{x}{\sqrt{5}} \right) + c$
