+### 1a) Limit Expression:
$\lim_{{x \to 3}} \frac{{x^2 - 9}}{{x - 3}}$

 #### 1a)  **Limit Expression:**
- <!-- $$ \large x^2 - 9$$ -->
 
- <br>
+
+
+<!--
+ <p align="center">  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} \\
+&= \lim_{x \to 3}(x+3) \\
+&= 3+3 
+&= 6
 \large \lim_{{x \to 3}} \frac{{x^2 - 9}}{{x - 3}}
 \end{align*}
 \$$

 *  **Simplified Form:** The numerator  $\large x^2 - 9$, can be factored as ( (x + 3)(x - 3) ), which simplifies the expression to:
