derivative y=((3x-6))/((x^2+4))

Lösung

ableitung von

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

Lösung

\frac{- 3 x ^{2} + 12 x + 12}{( x ^{2} + 4 ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{3 x - 6}{x ^{2} + 4})

Wende die Quotientenregel an:

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

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

\frac{d}{d x} (3 x - 6) = 3

\frac{d}{d x} (x^{2} + 4) = 2 x

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

3 (x^{2} + 4) - 2 x (3 x - 6) : - 3 x^{2} + 12 x + 12

= \frac{- 3 x ^{2} + 12 x + 12}{( x ^{2} + 4 ) ^{2}}
