derivative of (x^2-3/(x^2-4))

Lösung

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

- \frac{2 x}{( x ^{2} - 4 ) ^{2}}

Schritte zur Lösung

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

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

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

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

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

Vereinfache

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

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