\frac{d}{d x} (\frac{x + 7}{x})

\frac{x - 7}{2 x x}

Solution steps

\frac{d}{d x} (\frac{x + 7}{x})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( x + 7 ) x - \frac{d}{d x} ( x ) ( x + 7 )}{( x ) ^{2}}

\frac{d}{d x} (x + 7) = 1

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

= \frac{1 \cdot x - \frac{1}{2 x} ( x + 7 )}{( x ) ^{2}}

Simplify

\frac{1 \cdot x - \frac{1}{2 x} ( x + 7 )}{( x ) ^{2}} : \frac{x - 7}{2 x x}

= \frac{x - 7}{2 x x}
