= 14 \frac{\partial}{\partial x} (\frac{x}{7 x ^{2} + y ^{2} + 2})

Wende die Quotientenregel an:

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

= 14 \cdot \frac{\frac{\partial}{\partial x} ( x ) ( 7 x ^{2} + y ^{2} + 2 ) - \frac{\partial}{\partial x} ( 7 x ^{2} + y ^{2} + 2 ) x}{( 7 x ^{2} + y ^{2} + 2 ) ^{2}}

\frac{\partial}{\partial x} (x) = 1

\frac{\partial}{\partial x} (7 x^{2} + y^{2} + 2) = 14 x

= 14 \cdot \frac{1 \cdot ( 7 x ^{2} + y ^{2} + 2 ) - 14 xx}{( 7 x ^{2} + y ^{2} + 2 ) ^{2}}
