Learn how to solve integrals by partial fraction expansion problems step by step online. Find the integral int(x/(x^2+7x+6))dx. Rewrite the expression \frac{x}{x^2+7x+6} inside the integral in factored form. Rewrite the fraction \frac{x}{\left(x+1\right)\left(x+6\right)} in 2 simpler fractions using partial fraction decomposition. Expand the integral \int\left(\frac{-1}{5\left(x+1\right)}+\frac{6}{5\left(x+6\right)}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int\frac{-1}{5\left(x+1\right)}dx results in: -\frac{1}{5}\ln\left(x+1\right).

Final answer to the problem

$-\frac{1}{5}\ln\left|x+1\right|+\frac{6}{5}\ln\left|x+6\right|+C_0$
