derivative of (2+x/(1-x))

Solution

\frac{d}{d x} (\frac{2 + x}{1 - x})

Solution

\frac{3}{( 1 - x ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{2 + x}{1 - x})

Apply the Quotient Rule:

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

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

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

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

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

Simplify

\frac{1 \cdot ( 1 - x ) - ( - 1 ) ( 2 + x )}{( 1 - x ) ^{2}} : \frac{3}{( 1 - x ) ^{2}}

= \frac{3}{( 1 - x ) ^{2}}
