$\int\left(x+y+2\right)\left(x-y-2\right)dx$
Learn how to solve integral calculus problems step by step online. Find the integral of (x+y+2)(x-y+-2). Find the integral. Rewrite the integrand \left(x+y+2\right)\left(x-y-2\right) in expanded form. Expand the integral \int\left(x^2-y^2-4y-4\right)dx into 4 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int x^2dx results in: \frac{x^{3}}{3}.
