derivative of (2x+1/(x+5))

Lösung

\frac{d}{d x} (\frac{2 x + 1}{x + 5})

Lösung

\frac{9}{( x + 5 ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{2 x + 1}{x + 5})

Wende die Quotientenregel an:

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

= \frac{\frac{d}{d x} ( 2 x + 1 ) ( x + 5 ) - \frac{d}{d x} ( x + 5 ) ( 2 x + 1 )}{( x + 5 ) ^{2}}

\frac{d}{d x} (2 x + 1) = 2

\frac{d}{d x} (x + 5) = 1

= \frac{2 ( x + 5 ) - 1 \cdot ( 2 x + 1 )}{( x + 5 ) ^{2}}

Vereinfache

\frac{2 ( x + 5 ) - 1 \cdot ( 2 x + 1 )}{( x + 5 ) ^{2}} : \frac{9}{( x + 5 ) ^{2}}

= \frac{9}{( x + 5 ) ^{2}}
