ધારો કે $\alpha$ અને $\beta$ એ $5x^2 - 3x - 1 = 0$ ના બીજ છે. તો પદાવલિ $\left[ (\alpha + \beta)x - \left( \frac{\alpha^2 + \beta^2}{2} \right)x^2 + \left( \frac{\alpha^3 + \beta^3}{3} \right)x^3 - \dots \right]$ બરાબર શું થાય?

  • A
    $\ln(1 - \frac{3}{5}x - \frac{1}{5}x^2)$
  • B
    $\ln(1 + \frac{3}{5}x - \frac{1}{5}x^2)$
  • C
    $\ln(1 - \frac{3}{5}x + \frac{1}{5}x^2)$
  • D
    આપેલ પૈકી કોઈ નહીં
