derivative of

\frac{3}{4 x + 1}

- \frac{12}{( 4 x + 1 ) ^{2}}

Solution steps

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

Take the constant out:

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

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

3 (- \frac{1}{( 4 x + 1 ) ^{2}} \cdot 4) : - \frac{12}{( 4 x + 1 ) ^{2}}

= - \frac{12}{( 4 x + 1 ) ^{2}}
