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

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

Solution steps

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

Take the constant out:

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

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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