f'(x)  =  - ( 2/(x + 1)²  + x(3x - 2))/(3x - 1)²)      यदि f(x)  =  2/(x + 1)   - x²/(3x - 1)

Step-by-step explanation:

f(x) = xⁿ  => f'(x) = nxⁿ⁻¹

f(u)f(v)  = f(u)f'(v)  + f'(u'f(v)

f(u) + f(v)  = f'(u) + f'(v)

f(x)  =  2/(x + 1)   - x²/(3x - 1)

f(x) = 2(x + 1)⁻¹   - x² (3x - 1)⁻¹

 f'(x)  =  2(-1)(x + 1)⁻²  -  (   x² (-1)(3x - 1)⁻²(3)  +   2x(3x - 1)⁻¹ )

=>  f'(x)  =  -2/(x + 1)²  + 3x²/(3x - 1)²  - 2x/(3x - 1)

=>  f'(x)  =   -2/(x + 1)²  +    (3x²  - 6x² + 2x)/(3x - 1)²

=>  f'(x)  =  -2/(x + 1)²  + (2x - 3x²)/(3x - 1)²

=>  f'(x)  =  - ( 2/(x + 1)²  + x(3x - 2))/(3x - 1)²)

 f'(x)  =  - ( 2/(x + 1)²  + x(3x - 2))/(3x - 1)²)      यदि f(x)  =  2/(x + 1)   - x²/(3x - 1)
