$\int\frac{x^4+3x^2+4}{x+1}dx$
Learn how to solve differential calculus problems step by step online. Integrate the function (x^4+3x^2+4)/(x+1). Find the integral. Divide x^4+3x^2+4 by x+1. Resulting polynomial. Expand the integral \int\left(x^{3}-x^{2}+4x-4+\frac{8}{x+1}\right)dx into 5 integrals using the sum rule for integrals, to then solve each integral separately.
