$\frac{\left(x+3\right)\left(x-3\right)}{x-3}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit of (x^2-9)/(x-3) as x approaches 3. Factor the difference of squares x^2-9 as the product of two conjugated binomials. Simplify the fraction \frac{\left(x+3\right)\left(x-3\right)}{x-3} by x-3. Evaluate the limit \lim_{x\to3}\left(x+3\right) by replacing all occurrences of x by 3. Add the values 3 and 3.
