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