$\int\left(n-1\right)\left(n+1\right)dn$
Learn how to solve problems step by step online. Find the integral of (n-1)(n+1). Find the integral. Rewrite the integrand \left(n-1\right)\left(n+1\right) in expanded form. Expand the integral \int\left(n^2-1\right)dn into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int n^2dn results in: \frac{n^{3}}{3}.
