\frac{d}{d x} (\frac{8 x ^{2} + 4 x + 2}{x})

\frac{12 x ^{2} + 2 x - 1}{x x}

Solution steps

\frac{d}{d x} (\frac{8 x ^{2} + 4 x + 2}{x})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( 8 x ^{2} + 4 x + 2 ) x - \frac{d}{d x} ( x ) ( 8 x ^{2} + 4 x + 2 )}{( x ) ^{2}}

\frac{d}{d x} (8 x^{2} + 4 x + 2) = 16 x + 4

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

= \frac{( 16 x + 4 ) x - \frac{1}{2 x} ( 8 x ^{2} + 4 x + 2 )}{( x ) ^{2}}

Simplify

\frac{( 16 x + 4 ) x - \frac{1}{2 x} ( 8 x ^{2} + 4 x + 2 )}{( x ) ^{2}} : \frac{12 x ^{2} + 2 x - 1}{x x}

= \frac{12 x ^{2} + 2 x - 1}{x x}

\int_{1}^{\infty} \frac{x}{e ^{x}} d x

\frac{\partial}{\partial x} (60 x^{\frac{4}{5}} y^{\frac{1}{5}})

\int \frac{x}{4 - 9 x ^{2}} d x

\int 2 cos (\frac{nπ x}{2}) d x

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