derivative of (5x-7/(6x-9))

Lösung

\frac{d}{d x} (\frac{5 x - 7}{6 x - 9})

Lösung

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

Schritte zur Lösung

\frac{d}{d x} (\frac{5 x - 7}{6 x - 9})

Wende die Quotientenregel an:

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

= \frac{\frac{d}{d x} ( 5 x - 7 ) ( 6 x - 9 ) - \frac{d}{d x} ( 6 x - 9 ) ( 5 x - 7 )}{( 6 x - 9 ) ^{2}}

\frac{d}{d x} (5 x - 7) = 5

\frac{d}{d x} (6 x - 9) = 6

= \frac{5 ( 6 x - 9 ) - 6 ( 5 x - 7 )}{( 6 x - 9 ) ^{2}}

Vereinfache

\frac{5 ( 6 x - 9 ) - 6 ( 5 x - 7 )}{( 6 x - 9 ) ^{2}} : - \frac{1}{3 ( 2 x - 3 ) ^{2}}

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