\frac{d}{d x} (\frac{8 x}{8 + x})

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

Solution steps

\frac{d}{d x} (\frac{8 x}{8 + x})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 8 \frac{d}{d x} (\frac{x}{8 + x})

Apply the Quotient Rule:

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

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

\frac{d x}{d x} = 1

\frac{d}{d x} (8 + x) = \frac{1}{2 x}

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

Simplify

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

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