$\frac{3}{x^2\left(x^2-9\right)}=\frac{A}{x^2}+\frac{Bx+C}{x^2-9}+\frac{D}{x}$
Learn how to solve problems step by step online. Find the integral int(3/(x^2(x^2-9)))dx. Rewrite the fraction \frac{3}{x^2\left(x^2-9\right)} in 3 simpler fractions using partial fraction decomposition. Find the values for the unknown coefficients: A, B, C, D. The first step is to multiply both sides of the equation from the previous step by x^2\left(x^2-9\right). Multiplying polynomials. Simplifying.
