derivative of

f (x) = \frac{6 x + 8 x ^{2}}{( 3 + 8 x ) ^{2}}

\frac{18}{( 3 + 8 x ) ^{3}}

Solution steps

\frac{d}{d x} (\frac{6 x + 8 x ^{2}}{( 3 + 8 x ) ^{2}})

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{d}{d x} ( 6 x + 8 x ^{2} ) ( 3 + 8 x ) ^{2} - \frac{d}{d x} ( ( 3 + 8 x ) ^{2} ) ( 6 x + 8 x ^{2} )}{( ( 3 + 8 x ) ^{2} ) ^{2}}

\frac{d}{d x} (6 x + 8 x^{2}) = 6 + 16 x

\frac{d}{d x} ((3 + 8 x)^{2}) = 16 (3 + 8 x)

= \frac{( 6 + 16 x ) ( 3 + 8 x ) ^{2} - 16 ( 3 + 8 x ) ( 6 x + 8 x ^{2} )}{( ( 3 + 8 x ) ^{2} ) ^{2}}

Simplify

\frac{( 6 + 16 x ) ( 3 + 8 x ) ^{2} - 16 ( 3 + 8 x ) ( 6 x + 8 x ^{2} )}{( ( 3 + 8 x ) ^{2} ) ^{2}} : \frac{18}{( 3 + 8 x ) ^{3}}

= \frac{18}{( 3 + 8 x ) ^{3}}

\int_{- 1}^{1} π (x^{2} + 1)^{2} d x

\int \frac{6 x ^{5} - 12 x ^{4} + 9 x ^{3}}{3 x ^{2}} d x

\frac{d y}{d x} = 2 y x + y x^{2}

\int 7 θ cos (θ) d θ

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