$9\int\frac{x^2}{\left(64+x^2\right)^2}dx$
Learn how to solve problems step by step online. Find the integral int((9x^2)/((64+x^2)^2))dx. Take out the constant 9 from the integral. Rewrite the fraction \frac{x^2}{\left(64+x^2\right)^2} in 2 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(64+x^2\right)^2. Multiplying polynomials.
