derivative of

\frac{4}{2 x + 3}

- \frac{8}{( 2 x + 3 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{4}{2 x + 3})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 4 \frac{d}{d x} (\frac{1}{2 x + 3})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= 4 \frac{d}{d x} ((2 x + 3)^{- 1})

Apply the chain rule:

- \frac{1}{( 2 x + 3 ) ^{2}} \frac{d}{d x} (2 x + 3)

= - \frac{1}{( 2 x + 3 ) ^{2}} \frac{d}{d x} (2 x + 3)

\frac{d}{d x} (2 x + 3) = 2

= 4 (- \frac{1}{( 2 x + 3 ) ^{2}} \cdot 2)

Simplify

4 (- \frac{1}{( 2 x + 3 ) ^{2}} \cdot 2) : - \frac{8}{( 2 x + 3 ) ^{2}}

= - \frac{8}{( 2 x + 3 ) ^{2}}
