$\int\left(a-b-c-d\right)^2db$
Learn how to solve problems step by step online. Integrate the function (a-b-c-d)^2. Find the integral. Rewrite the integrand \left(a-b-c-d\right)^2 in expanded form. Expand the integral \int\left(a^2+b^2+c^2+2cd+d^2-2ab-2ca-2da+2cb+2db\right)db into 10 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int a^2db results in: \frac{a^{3}}{3}.
