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

\frac{12 ( 3 x - 1 ) ^{3}}{( 2 x + 1 ) ^{3}} - \frac{6 ( 3 x - 1 ) ^{4}}{( 2 x + 1 ) ^{4}}

Solution steps

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

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = (3 x - 1)^{4}, g = (2 x + 1)^{- 3}

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

\frac{d}{d x} ((3 x - 1)^{4}) = 12 (3 x - 1)^{3}

\frac{d}{d x} ((2 x + 1)^{- 3}) = - \frac{6}{( 2 x + 1 ) ^{4}}

= 12 (3 x - 1)^{3} (2 x + 1)^{- 3} + (- \frac{6}{( 2 x + 1 ) ^{4}}) (3 x - 1)^{4}

Simplify

12 (3 x - 1)^{3} (2 x + 1)^{- 3} + (- \frac{6}{( 2 x + 1 ) ^{4}}) (3 x - 1)^{4} : \frac{12 ( 3 x - 1 ) ^{3}}{( 2 x + 1 ) ^{3}} - \frac{6 ( 3 x - 1 ) ^{4}}{( 2 x + 1 ) ^{4}}

= \frac{12 ( 3 x - 1 ) ^{3}}{( 2 x + 1 ) ^{3}} - \frac{6 ( 3 x - 1 ) ^{4}}{( 2 x + 1 ) ^{4}}
