$\int_{1}^{2}2xdx+\int_{1}^{2}5dx$
Learn how to solve power of a product problems step by step online. Integrate the function 2x+5 from 1 to 2. Expand the integral \int_{1}^{2}\left(2x+5\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int_{1}^{2}2xdx results in: 3. The integral \int_{1}^{2}5dx results in: 5. Gather the results of all integrals.
