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