$\begin{matrix}\left(1\right)\left(-4\right)=-4\\ \left(1\right)+\left(-4\right)=-3\end{matrix}$
Learn how to solve integrals by partial fraction expansion problems step by step online. Find the integral int(5/(x^2-3x+-4))dx. Factor the trinomial x^2-3x-4 finding two numbers that multiply to form -4 and added form -3. Thus. Rewrite the fraction \frac{5}{\left(x+1\right)\left(x-4\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-4\right).
