$\int\frac{x^2-2x+1}{x^2-1}dx$
Learn how to solve integral calculus problems step by step online. Integrate the function (x^2-2x+1)/(x^2-1). Find the integral. Rewrite the expression \frac{x^2-2x+1}{x^2-1} inside the integral in factored form. Simplify the fraction \frac{\left(x-1\right)^{2}}{\left(x+1\right)\left(x-1\right)} by x-1. Expand the fraction \frac{x-1}{x+1} into 2 simpler fractions with common denominator x+1.
