\frac{d}{d x} (\frac{11 x}{( 2 + x ^{2} )})

\frac{11 ( 2 - x ^{2} )}{( 2 + x ^{2} ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{11 x}{( 2 + x ^{2} )})

Take the constant out:

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

= 11 \frac{d}{d x} (\frac{x}{2 + x ^{2}})

Apply the Quotient Rule:

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

= 11 \cdot \frac{\frac{d x}{d x} ( 2 + x ^{2} ) - \frac{d}{d x} ( 2 + x ^{2} ) x}{( 2 + x ^{2} ) ^{2}}

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

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

= 11 \cdot \frac{1 \cdot ( 2 + x ^{2} ) - 2 xx}{( 2 + x ^{2} ) ^{2}}

Simplify

11 \cdot \frac{1 \cdot ( 2 + x ^{2} ) - 2 xx}{( 2 + x ^{2} ) ^{2}} : \frac{11 ( 2 - x ^{2} )}{( 2 + x ^{2} ) ^{2}}

= \frac{11 ( 2 - x ^{2} )}{( 2 + x ^{2} ) ^{2}}
