Learn how to solve problems step by step online. Find the integral int((6x^2)/(x^4-5x^2+4))dx. Rewrite the expression \frac{6x^2}{x^4-5x^2+4} inside the integral in factored form. Take out the constant 6 from the integral. Rewrite the fraction \frac{x^2}{\left(x+1\right)\left(x+2\right)\left(x-2\right)\left(x-1\right)} in 4 simpler fractions using partial fraction decomposition. Expand the integral \int\left(\frac{1}{6\left(x+1\right)}+\frac{-1}{3\left(x+2\right)}+\frac{1}{3\left(x-2\right)}+\frac{-1}{6\left(x-1\right)}\right)dx into 4 integrals using the sum rule for integrals, to then solve each integral separately.
