(\partial)/(\partial x)((3y-6x)/(y^2+7x^2))

Lösung

\frac{\partial}{\partial x} (\frac{3 y - 6 x}{y ^{2} + 7 x ^{2}})

\frac{42 x ^{2} - 42 y x - 6 y ^{2}}{( y ^{2} + 7 x ^{2} ) ^{2}}

Schritte zur Lösung

\frac{\partial}{\partial x} (\frac{3 y - 6 x}{y ^{2} + 7 x ^{2}})

Behandle

y

als Konstante

Wende die Quotientenregel an:

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

= \frac{\frac{\partial}{\partial x} ( 3 y - 6 x ) ( y ^{2} + 7 x ^{2} ) - \frac{\partial}{\partial x} ( y ^{2} + 7 x ^{2} ) ( 3 y - 6 x )}{( y ^{2} + 7 x ^{2} ) ^{2}}

\frac{\partial}{\partial x} (3 y - 6 x) = - 6

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

= \frac{( - 6 ) ( y ^{2} + 7 x ^{2} ) - 14 x ( 3 y - 6 x )}{( y ^{2} + 7 x ^{2} ) ^{2}}

Vereinfache

\frac{( - 6 ) ( y ^{2} + 7 x ^{2} ) - 14 x ( 3 y - 6 x )}{( y ^{2} + 7 x ^{2} ) ^{2}} : \frac{42 x ^{2} - 42 y x - 6 y ^{2}}{( y ^{2} + 7 x ^{2} ) ^{2}}

= \frac{42 x ^{2} - 42 y x - 6 y ^{2}}{( y ^{2} + 7 x ^{2} ) ^{2}}
