$\int\left(3y+x\right)\left(3y-x\right)dx$
Learn how to solve integral calculus problems step by step online. Integrate the function (3y+x)(3y-x). Find the integral. Rewrite the integrand \left(3y+x\right)\left(3y-x\right) in expanded form. Expand the integral \int\left(9y^2-x^2\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int9y^2dx results in: 3y^{3}.
