$\frac{\left(x+9\right)\left(x-9\right)}{x-9}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit of (x^2-81)/(x-9) as x approaches 9. Factor the difference of squares x^2-81 as the product of two conjugated binomials. Simplify the fraction \frac{\left(x+9\right)\left(x-9\right)}{x-9} by x-9. Evaluate the limit \lim_{x\to9}\left(x+9\right) by replacing all occurrences of x by 9. Add the values 9 and 9.
