$\int\left(-x-y-z\right)^2dx$
Learn how to solve integral calculus problems step by step online. Integrate the function (-x-y-z)^2. Find the integral. Rewrite the integrand \left(-x-y-z\right)^2 in expanded form. Expand the integral \int\left(x^2+y^2+z^2+2xy+2xz+2yz\right)dx into 6 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int x^2dx results in: \frac{x^{3}}{3}.
