#### Explanation:

The differential coefficient of a fraction is given by (Denominator * Diff. Coeff. of Numerator - Numerator * Diff. Coeff. of Denominator) / Denominator^2

Here DC of Denominator = 2x

and DC of Numerator = 4

Substituting we get

Expanding we get

Simplifying, we get

ie

Hope it is clear
