Learn how to solve definite integrals problems step by step online. Find the integral int((x-1)/(x^2+3x+2))dx. Factor the trinomial x^2+3x+2 finding two numbers that multiply to form 2 and added form 3. Thus. Rewrite the fraction \frac{x-1}{\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).
