$\int\frac{1}{\left(x+3\right)\left(x-3\right)}dx$
Learn how to solve integrals by partial fraction expansion problems step by step online. Find the integral int(1/(x^2-9))dx. Rewrite the expression \frac{1}{x^2-9} inside the integral in factored form. Rewrite the fraction \frac{1}{\left(x+3\right)\left(x-3\right)} in 2 simpler fractions using partial fraction decomposition. Expand the integral \int\left(\frac{-1}{6\left(x+3\right)}+\frac{1}{6\left(x-3\right)}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int\frac{-1}{6\left(x+3\right)}dx results in: -\frac{1}{6}\ln\left(x+3\right).
