derivative of x/(5-x)

Solution

derivative of

\frac{x}{5 - x}

Solution

\frac{5}{( 5 - x ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x}{5 - x})

Apply the Quotient Rule:

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

= \frac{\frac{d x}{d x} ( 5 - x ) - \frac{d}{d x} ( 5 - x ) x}{( 5 - x ) ^{2}}

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

\frac{d}{d x} (5 - x) = - 1

= \frac{1 \cdot ( 5 - x ) - ( - 1 ) x}{( 5 - x ) ^{2}}

Simplify

\frac{1 \cdot ( 5 - x ) - ( - 1 ) x}{( 5 - x ) ^{2}} : \frac{5}{( 5 - x ) ^{2}}

= \frac{5}{( 5 - x ) ^{2}}
