$\frac{{\left(-1\right)}^2-4}{-1+2}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(-1)lim((x^2-4)/(x+2)). Evaluate the limit \lim_{x\to-1}\left(\frac{x^2-4}{x+2}\right) by replacing all occurrences of x by -1. Subtract the values 2 and -1. Calculate the power {\left(-1\right)}^2. Subtract the values 1 and -4.
