$d\int\frac{4x^3-6x^2+2x-5}{x^4+x^2}dx$
Learn how to solve integral calculus problems step by step online. Find the integral int((4x^3-6x^22x+-5)/(x^4+x^2)d)dx. Simplify the expression inside the integral. Rewrite the expression \frac{4x^3-6x^2+2x-5}{x^4+x^2} inside the integral in factored form. Rewrite the fraction \frac{4x^3-6x^2+2x-5}{x^2\left(x^2+1\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+1\right).
