$\frac{x+1}{\left(x+1\right)\left(x-1\right)}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit of (x+1)/(x^2-1) as x approaches -1. Factor the difference of squares x^2-1 as the product of two conjugated binomials. Simplify the fraction . Evaluate the limit \lim_{x\to-1}\left(\frac{1}{x-1}\right) by replacing all occurrences of x by -1. Subtract the values -1 and -1.
