Learn how to solve definite integrals problems step by step online. Integrate the function (4x^2-7)/(2x+3) from -1 to 3. Divide 4x^2-7 by 2x+3. Resulting polynomial. Expand the integral \int_{-1}^{3}\left(2x-3+\frac{2}{2x+3}\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. We can solve the integral \int_{-1}^{3}\frac{2}{2x+3}dx by applying integration by substitution method (also called U-Substitution). First, we must identify a section within the integral with a new variable (let's call it u), which when substituted makes the integral easier. We see that 2x+3 it's a good candidate for substitution. Let's define a variable u and assign it to the choosen part.
