$\int\frac{5x^2+3}{x^2-2x-3}dx$
Learn how to solve equations problems step by step online. Find the integral int((5x^2+3)/(x^2+1*-2x+-3))dx. Simplifying. Divide 5x^2+3 by x^2-2x-3. Resulting polynomial. Expand the integral \int\left(5+\frac{10x+18}{x^2-2x-3}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately.
