derivative of (x^2-3x+2/(x^7-2))

Lösung

\frac{d}{d x} (\frac{x ^{2} - 3 x + 2}{x ^{7} - 2})

\frac{- 5 x ^{8} + 18 x ^{7} - 14 x ^{6} - 4 x + 6}{( x ^{7} - 2 ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{x ^{2} - 3 x + 2}{x ^{7} - 2})

Wende die Quotientenregel an:

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

= \frac{\frac{d}{d x} ( x ^{2} - 3 x + 2 ) ( x ^{7} - 2 ) - \frac{d}{d x} ( x ^{7} - 2 ) ( x ^{2} - 3 x + 2 )}{( x ^{7} - 2 ) ^{2}}

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

\frac{d}{d x} (x^{7} - 2) = 7 x^{6}

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