Learn how to solve integrals by partial fraction expansion problems step by step online. Find the integral int((3x+8)/(x^2+4x+3))dx. Factor the trinomial x^2+4x+3 finding two numbers that multiply to form 3 and added form 4. Thus. Rewrite the fraction \frac{3x+8}{\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).
