$\int3xdx+27\int\frac{x}{x^2-9}dx$
Learn how to solve integrals of polynomial functions problems step by step online. Integrate int(3x+(27x)/(x^2-9))dx. Simplify the expression inside the integral. Factor the difference of squares x^2-9 as the product of two conjugated binomials. Rewrite the fraction \frac{x}{\left(x+3\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+3\right)\left(x-3\right).
