als Konstante

Wende die Quotientenregel an:

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

= \frac{\frac{\partial}{\partial x} ( 3 x - 2 y ) ( x ^{2} + 3 y ) - \frac{\partial}{\partial x} ( x ^{2} + 3 y ) ( 3 x - 2 y )}{( x ^{2} + 3 y ) ^{2}}

\frac{\partial}{\partial x} (3 x - 2 y) = 3

\frac{\partial}{\partial x} (x^{2} + 3 y) = 2 x

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