Lösung

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

\frac{- 6 x ^{2} + 8 x + 1}{( 2 - 3 x ) ^{2}}

Schritte zur Lösung

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

Wende die Quotientenregel an:

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

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

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

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

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

= \frac{- 6 x ^{2} + 8 x + 1}{( 2 - 3 x ) ^{2}}
