$3\int\frac{x}{\left(x+4\right)\left(x+1\right)}dx$
Learn how to solve problems step by step online. Find the integral int((3x)/((x+4)(x+1)))dx. Take out the constant 3 from the integral. Rewrite the fraction \frac{x}{\left(x+4\right)\left(x+1\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+1\right). Multiplying polynomials.
