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

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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

5 \cdot i (t)

\frac{x ^{\frac{1}{3}} - 4}{x ^{\frac{7}{2}}}

y^{^{''}} + 10 y^{^{'}} + 25 y = - 50 e^{- 5 x}

\int \frac{e ^{x}}{( e ^{x} - 5 ) ( e ^{x} - 11 )} d x

\int_{2}^{6} (x^{2} - 7 x + 6) d x
