Learn how to solve definite integrals problems step by step online. Integrate the function 1/(x^2-x+-2) from 0 to infinity. Factor the trinomial x^2-x-2 finding two numbers that multiply to form -2 and added form -1. Thus. Rewrite the fraction \frac{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).
