જો $\alpha, \beta$ એ સમીકરણ $x^2 - px + q = 0$ ના બીજ હોય,તો $\log_e(1 + px + qx^2) = $

  • A
    $(\alpha + \beta)x - \frac{\alpha^2 + \beta^2}{2}x^2 + \frac{\alpha^3 + \beta^3}{3}x^3 - \dots \infty$
  • B
    $(\alpha + \beta)x - \frac{(\alpha + \beta)^2}{2}x^2 + \frac{(\alpha + \beta)^3}{3}x^3 - \dots \infty$
  • C
    $(\alpha + \beta)x + \frac{\alpha^2 + \beta^2}{2}x^2 + \frac{\alpha^3 + \beta^3}{3}x^3 + \dots \infty$
  • D
    આમાંથી કોઈ નહીં
