Learn how to solve integrals by partial fraction expansion problems step by step online. Find the integral int((x-11)/(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{x-11}{\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).
