derivative of

x - 2 ln (x + 1)

1 - \frac{2}{x + 1}

Solution steps

\frac{d}{d x} (x - 2 ln (x + 1))

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

\frac{d x}{d x} = 1

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

= 1 - \frac{2}{x + 1}
