$\int\frac{x^2-1}{x-1}dx$
Learn how to solve problems step by step online. Find the integral of (x^2-1)/(x-1). Find the integral. Rewrite the expression \frac{x^2-1}{x-1} inside the integral in factored form. Expand the integral \int\left(x+1\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.
