Final answer to the problem
Step-by-step Solution
Specify the solving method
The difference of the squares of two terms, divided by the sum of the same terms, is equal to the difference of the terms. In other words: $\displaystyle\frac{a^2-b^2}{a+b}=a-b$.

Learn how to solve limits by direct substitution problems step by step online. Find the limit of (x^2-1)/(x+1) as x approaches 1. The difference of the squares of two terms, divided by the sum of the same terms, is equal to the difference of the terms. In other words: \displaystyle\frac{a^2-b^2}{a+b}=a-b.. Evaluate the limit \lim_{x\to1}\left(x-1\right) by replacing all occurrences of x by 1. Subtract the values 1 and -1.
