derivative ((12x-7))/(3x-9)

Lösung

ableitung von

\frac{( 12 x - 7 )}{3 x - 9}

Lösung

- \frac{29}{3 ( x - 3 ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{12 x - 7}{3 x - 9})

Wende die Quotientenregel an:

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

= \frac{\frac{d}{d x} ( 12 x - 7 ) ( 3 x - 9 ) - \frac{d}{d x} ( 3 x - 9 ) ( 12 x - 7 )}{( 3 x - 9 ) ^{2}}

\frac{d}{d x} (12 x - 7) = 12

\frac{d}{d x} (3 x - 9) = 3

= \frac{12 ( 3 x - 9 ) - 3 ( 12 x - 7 )}{( 3 x - 9 ) ^{2}}

Vereinfache

\frac{12 ( 3 x - 9 ) - 3 ( 12 x - 7 )}{( 3 x - 9 ) ^{2}} : - \frac{29}{3 ( x - 3 ) ^{2}}

= - \frac{29}{3 ( x - 3 ) ^{2}}
