$\frac{x^2+3}{\left(x+1\right)\left(x^2+1\right)}=\frac{A}{x+1}+\frac{Bx+C}{x^2+1}$
Learn how to solve problems step by step online. Integrate the function (x^2+3)/((x+1)(x^2+1)) from 0 to 1. Rewrite the fraction \frac{x^2+3}{\left(x+1\right)\left(x^2+1\right)} in 2 simpler fractions using partial fraction decomposition. Find the values for the unknown coefficients: A, B, C. The first step is to multiply both sides of the equation from the previous step by \left(x+1\right)\left(x^2+1\right). Multiply both sides of the equality by 1 to simplify the fractions.
