Learn how to solve integrals of rational functions problems step by step online. Find the integral int(((x+1)(x-1))/x)dx. Rewrite the integrand \frac{\left(x+1\right)\left(x-1\right)}{x} in expanded form. Expand the integral \int\left(x+\frac{-1}{x}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int xdx results in: \frac{1}{2}x^2. The integral \int\frac{-1}{x}dx results in: -\ln\left(x\right).
