derivative of

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

\frac{10}{( x + 1 ) ^{3}}

Solution steps

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

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

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

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

Simplify

\frac{( 2 x + 2 ) ( x + 1 ) ^{2} - 2 ( x + 1 ) ( x ^{2} + 2 x - 4 )}{( ( x + 1 ) ^{2} ) ^{2}} : \frac{10}{( x + 1 ) ^{3}}

= \frac{10}{( x + 1 ) ^{3}}

\int \frac{6 x + 5}{x ^{2} + 3 x - 4} d x

\int (4 x + e^{x}) sin (6 x^{2} + 3 e^{x}) d x

\int \frac{1 - x}{1 + x ^{2}} d x

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

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