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

\frac{24 x ( - x ^{2} + 1 )}{( x ^{2} + 1 ) ^{4}}

Solution steps

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

Simplify

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

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

- 2 \cdot \frac{( - 6 x ) ( 1 + x ^{2} ) ^{3} - 6 x ( 1 + x ^{2} ) ^{2} ( - 3 x ^{2} + 1 )}{( ( 1 + x ^{2} ) ^{3} ) ^{2}} : \frac{24 x ( - x ^{2} + 1 )}{( x ^{2} + 1 ) ^{4}}

= \frac{24 x ( - x ^{2} + 1 )}{( x ^{2} + 1 ) ^{4}}

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

\int x^{4} (x^{5} + 1)^{18} d x

\frac{\partial}{\partial x} (x^{3} y^{2})

\int 7 x e^{- x^{2}} d x

y = ln (ln (2 x))
