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

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

\frac{2 x ( 4 - x ^{2} ) - ( - 2 x ) ( x ^{2} - 1 )}{( 4 - x ^{2} ) ^{2}} : \frac{6 x}{( 4 - x ^{2} ) ^{2}}

= \frac{6 x}{( 4 - x ^{2} ) ^{2}}

\int \frac{7}{x ( x ^{4} + 2 )} d x

(ln (x))^{x}

\int 4 t^{2} + 9 t^{4} d t

\frac{d y}{d x} + cos (x) y = cos (x)

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