\frac{d}{d x} (\frac{x - 6}{x + 4})

\frac{5}{x ( x + 4 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x - 6}{x + 4})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( x - 6 ) ( x + 4 ) - \frac{d}{d x} ( x + 4 ) ( x - 6 )}{( x + 4 ) ^{2}}

\frac{d}{d x} (x - 6) = \frac{1}{2 x}

\frac{d}{d x} (x + 4) = \frac{1}{2 x}

= \frac{\frac{1}{2 x} ( x + 4 ) - \frac{1}{2 x} ( x - 6 )}{( x + 4 ) ^{2}}

Simplify

\frac{\frac{1}{2 x} ( x + 4 ) - \frac{1}{2 x} ( x - 6 )}{( x + 4 ) ^{2}} : \frac{5}{x ( x + 4 ) ^{2}}

= \frac{5}{x ( x + 4 ) ^{2}}
