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

Final Answer
