\frac{d}{d x} (\frac{2 x + 5}{x ^{2} - 1})

\frac{- 2 x ^{2} - 10 x - 2}{( x ^{2} - 1 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{2 x + 5}{x ^{2} - 1})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( 2 x + 5 ) ( x ^{2} - 1 ) - \frac{d}{d x} ( x ^{2} - 1 ) ( 2 x + 5 )}{( x ^{2} - 1 ) ^{2}}

\frac{d}{d x} (2 x + 5) = 2

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

= \frac{2 ( x ^{2} - 1 ) - 2 x ( 2 x + 5 )}{( x ^{2} - 1 ) ^{2}}

Expand

2 (x^{2} - 1) - 2 x (2 x + 5) : - 2 x^{2} - 10 x - 2

= \frac{- 2 x ^{2} - 10 x - 2}{( x ^{2} - 1 ) ^{2}}

f (x) = 2 x^{3} + 1

\int - \frac{4}{x ^{5}} d x

f (x) = - 3 x^{4}

\int_{0}^{π} 9 sin^{4} (x) d x

y = (cos (7 x))^{x}
