\frac{d}{d x} (\frac{- x ^{2} - 5}{( x ^{2} - 5 ) ^{2}})

- \frac{2 x ( - x ^{2} - 15 )}{( x ^{2} - 5 ) ^{3}}

Solution steps

\frac{d}{d x} (\frac{- x ^{2} - 5}{( x ^{2} - 5 ) ^{2}})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( - x ^{2} - 5 ) ( x ^{2} - 5 ) ^{2} - \frac{d}{d x} ( ( x ^{2} - 5 ) ^{2} ) ( - x ^{2} - 5 )}{( ( x ^{2} - 5 ) ^{2} ) ^{2}}

\frac{d}{d x} (- x^{2} - 5) = - 2 x

\frac{d}{d x} ((x^{2} - 5)^{2}) = 4 x (x^{2} - 5)

= \frac{( - 2 x ) ( x ^{2} - 5 ) ^{2} - 4 x ( x ^{2} - 5 ) ( - x ^{2} - 5 )}{( ( x ^{2} - 5 ) ^{2} ) ^{2}}

Simplify

\frac{( - 2 x ) ( x ^{2} - 5 ) ^{2} - 4 x ( x ^{2} - 5 ) ( - x ^{2} - 5 )}{( ( x ^{2} - 5 ) ^{2} ) ^{2}} : - \frac{2 x ( - x ^{2} - 15 )}{( x ^{2} - 5 ) ^{3}}

= - \frac{2 x ( - x ^{2} - 15 )}{( x ^{2} - 5 ) ^{3}}

\int e^{2 x} - x e^{2 x} d x
