derivative of

\frac{2 x + 9}{x}

\frac{2 x - 9}{2 x x}

Solution steps

\frac{d}{d x} (\frac{2 x + 9}{x})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( 2 x + 9 ) x - \frac{d}{d x} ( x ) ( 2 x + 9 )}{( x ) ^{2}}

\frac{d}{d x} (2 x + 9) = 2

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

= \frac{2 x - \frac{1}{2 x} ( 2 x + 9 )}{( x ) ^{2}}

Simplify

\frac{2 x - \frac{1}{2 x} ( 2 x + 9 )}{( x ) ^{2}} : \frac{2 x - 9}{2 x x}

= \frac{2 x - 9}{2 x x}
