derivative of

\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 - x^{7} \cdot e^{x^{8} - 7} - 2 x d x

\int 14 x e^{7 x} d x

x \to 3 lim (\frac{3}{x ^{2} - 9})

f (θ) = 4 tan (θ)

\frac{d}{d x} (2 cos (x) - cos (2 x))
