\frac{( 2 - \frac{1}{x} )}{x - 3}

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

Schritte zur Lösung

\frac{d}{d x} (\frac{2 - \frac{1}{x}}{x - 3})

Wende die Quotientenregel an:

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

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

\frac{d}{d x} (2 - \frac{1}{x}) = \frac{1}{x ^{2}}

\frac{d}{d x} (x - 3) = 1

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