\frac{( 6 + 7 x )}{( x ^{4} + 5 x - 5 )}

\frac{- 21 x ^{4} - 24 x ^{3} - 65}{( x ^{4} + 5 x - 5 ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{6 + 7 x}{x ^{4} + 5 x - 5})

Wende die Quotientenregel an:

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

= \frac{\frac{d}{d x} ( 6 + 7 x ) ( x ^{4} + 5 x - 5 ) - \frac{d}{d x} ( x ^{4} + 5 x - 5 ) ( 6 + 7 x )}{( x ^{4} + 5 x - 5 ) ^{2}}

\frac{d}{d x} (6 + 7 x) = 7

\frac{d}{d x} (x^{4} + 5 x - 5) = 4 x^{3} + 5

= \frac{7 ( x ^{4} + 5 x - 5 ) - ( 4 x ^{3} + 5 ) ( 6 + 7 x )}{( x ^{4} + 5 x - 5 ) ^{2}}
