$\int\frac{x^3-3x^2+4x-9}{x^2+3}dx$
Learn how to solve integrals of rational functions problems step by step online. Find the integral int((x^3+1*-3x^24x+-9)/(x^2+3))dx. Simplifying. Divide x^3-3x^2+4x-9 by x^2+3. Resulting polynomial. Expand the integral \int\left(x-3+\frac{x}{x^2+3}\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately.
