integral of 1/((x+1)^2)

\int \frac{1}{( x + 1 ) ^{2}} d x

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

Solution steps

\int \frac{1}{( x + 1 ) ^{2}} d x

Apply u-substitution

= \int \frac{1}{u ^{2}} d u

Apply the Power Rule

= - \frac{1}{u}

Substitute back

u = x + 1

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

Add a constant to the solution

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