$\int\frac{2x^3-x}{\left(x+3\right)^2\left(x-3\right)^2}dx$
Learn how to solve integrals by partial fraction expansion problems step by step online. Find the integral int((2x^3-x)/((x^2-9)^2))dx. Factor the difference of squares \left(x^2-9\right) as the product of two conjugated binomials. Rewrite the fraction \frac{2x^3-x}{\left(x+3\right)^2\left(x-3\right)^2} in 4 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 \left(x+3\right)^2\left(x-3\right)^2. Multiplying polynomials.
