derivative of

y = \frac{2 x ^{2} + 8 x + 4}{x}

\frac{3 x ^{2} + 4 x - 2}{x x}

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

\frac{( 4 x + 8 ) x - \frac{1}{2 x} ( 2 x ^{2} + 8 x + 4 )}{( x ) ^{2}} : \frac{3 x ^{2} + 4 x - 2}{x x}

= \frac{3 x ^{2} + 4 x - 2}{x x}
