$\int_{2}^{4}\left(\frac{4}{x^{2}}+12+9x^{2}\right)dx$
Learn how to solve definite integrals problems step by step online. Integrate the function (2/x+3x)^2 from 2 to 4. Rewrite the integrand \left(\frac{2}{x}+3x\right)^2 in expanded form. Expand the integral \int_{2}^{4}\left(\frac{4}{x^{2}}+12+9x^{2}\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int_{2}^{4}\frac{4}{x^{2}}dx results in: 1. The integral \int_{2}^{4}12dx results in: 24.
