Lösung

\frac{d}{d x} (\frac{( x ^{2} - 2 e ^{x} )}{x + 3 e ^{x}})

\frac{x ^{2} - 3 e ^{x} x ^{2} + 4 e ^{x} x + 2 e ^{x}}{( x + 3 e ^{x} ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{( x ^{2} - 2 e ^{x} )}{x + 3 e ^{x}})

Wende die Quotientenregel an:

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

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

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

\frac{d}{d x} (x + 3 e^{x}) = 1 + 3 e^{x}

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