Learn how to solve limits problems step by step online. Evaluate the limit of (x^2-3x+2)/(x^2-1) as x approaches -1. Factor the difference of squares x^2-1 as the product of two conjugated binomials. Factor the trinomial x^2-3x+2 finding two numbers that multiply to form 2 and added form -3. Thus. Simplifying.
