$\int\frac{1}{\left(x+1\right)^2\left(x^2+1\right)}dx$
Learn how to solve integral calculus problems step by step online. Find the integral of 1/((x+1)^2(x^2+1)). Find the integral. Rewrite the fraction \frac{1}{\left(x+1\right)^2\left(x^2+1\right)} in 3 simpler fractions using partial fraction decomposition. Find the values for the unknown coefficients: A, B, C, D. The first step is to multiply both sides of the equation from the previous step by \left(x+1\right)^2\left(x^2+1\right). Multiplying polynomials.
