   This is because the factor ( x - 3 ) in the denominator cancels out with the same factor in the numerator, leaving ( x + 3 ) which evaluates to 6 when ( x ) is 3.

- To solve this limit, we can use factorization:
- 
-$$\\begin{align*}
-\lim_{x \to 3}\frac{x^{2}-9}{x-3} &= \lim_{x \to 3}\frac{(x+3)(x-3)}{x-3} \\
