derivative of

\frac{( 2 x + x ^{2} )}{( 1 + x ) ^{2}}

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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

\frac{d y}{d x} = \frac{1}{4 - x ^{2}}

ln (x (1 - x)^{8})

\frac{d ^{2}}{d x ^{2}} (e^{7 x^{2}})

\frac{d ^{2}}{d r ( T ) d T} (r (T) (T)^{2} \frac{d ^{2}}{d r ( T ) d T} (T))

\frac{d}{d x} (cos (3))
