Learn how to solve integrals by partial fraction expansion problems step by step online. Find the integral int(33/(x^2+3x+-28))dx. Factor the trinomial x^2+3x-28 finding two numbers that multiply to form -28 and added form 3. Thus. Rewrite the fraction \frac{33}{\left(x-4\right)\left(x+7\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-4\right)\left(x+7\right).
