$\frac{x^2-2x+1+1-1}{x^2-1}$
Learn how to solve polynomial factorization problems step by step online. Factor by completing the square (x^2-2x+1)/(x^2-1). Add and subtract \displaystyle\left(\frac{b}{2a}\right)^2. Factor the perfect square trinomial x^2+-2x+1. Subtract the values 1 and -1. Factor the difference of squares x^2-1 as the product of two conjugated binomials.
