Learn how to solve limits by factoring 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. Evaluate the limit by replacing all occurrences of x by -1. Simplifying. section:If the limit is undefined, we need to find the left side and right side limits.
