$\begin{matrix}\left(-2\right)\left(6\right)=-12\\ \left(-2\right)+\left(6\right)=4\end{matrix}$
Learn how to solve problems step by step online. Find the integral int((x+5)/(x^2+4x+-12))dx. Factor the trinomial x^2+4x-12 finding two numbers that multiply to form -12 and added form 4. Thus. Rewrite the fraction \frac{x+5}{\left(x-2\right)\left(x+6\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-2\right)\left(x+6\right).
