Expand Integrand: Expand the integrand x2(3x−4)(x−3) to simplify the integral.We have the integral of a product of a quadratic and a linear term. We will first expand this product before integrating term by term.x2(3x−4)(x−3)=x2(3x2−9x−4x+12)=x2(3x2−13x+12)=3x4−13x3+12x2Now we can integrate each term separately.
Integrate Expanded Polynomial: Integrate each term of the expanded polynomial separately.The integral of 3x4 with respect to x is (53)x5, the integral of −13x3 with respect to x is (−413)x4, and the integral of 12x2 with respect to x is (312)x3 or 4x3.So, x0, where x1 is the constant of integration.
