$\int\frac{x^2}{x^3+3x+1+3x^2}dx$
Learn how to solve integral calculus problems step by step online. Integrate the function (x^2)/(x^3+3x+13x^2). Find the integral. Rewrite the expression \frac{x^2}{x^3+3x+1+3x^2} inside the integral in factored form. Rewrite the fraction \frac{x^2}{\left(x+1\right)^{3}} in 3 simpler fractions using partial fraction decomposition. Find the values for the unknown coefficients: A, B, C. The first step is to multiply both sides of the equation from the previous step by \left(x+1\right)^{3}.
