# (Ax + B) (A + D)2 - Mathematics

(ax + b) (a + d)2

#### Solution

$(ax + b)(a + d )^2$
$\text{ Let } u = ax + b, v = \left( a + d \right)^2$
$\text{ Then }, u' = a, v' = 0$
$\text{ Using the product rule }:$
$\frac{d}{dx}\left( uv \right) = u v' + v u'$
$\frac{d}{dx}\left( (ax + b)(a + d )^2 \right) = (ax + b) \times 0 + \left( a + d \right)^2 \times a$
$\therefore \frac{d}{dx}\left( (ax + b)(a + d )^2 \right) = a \left( a + d \right)^2$
