1. **State the problem:** Simplify the expression $$\frac{x}{x-3} + \frac{2}{x^2-3}$$.
2. **Identify the denominators:** The denominators are $x-3$ and $x^2-3$.
3. **Factor the second denominator if possible:**
$$x^2 - 3$$ cannot be factored further using integers, so it remains as is.
4. **Find a common denominator:** The common denominator is $$ (x-3)(x^2-3) $$.
5. **Rewrite each fraction with the common denominator:**
$$\frac{x}{x-3} = \frac{x(x^2-3)}{(x-3)(x^2-3)}$$
$$\frac{2}{x^2-3} = \frac{2(x-3)}{(x-3)(x^2-3)}$$
6. **Add the numerators:**
$$\frac{x(x^2-3) + 2(x-3)}{(x-3)(x^2-3)}$$
7. **Expand the numerators:**
$$x(x^2-3) = x^3 - 3x$$
$$2(x-3) = 2x - 6$$
8. **Combine the numerator terms:**
$$x^3 - 3x + 2x - 6 = x^3 - x - 6$$
9. **Final expression:**
$$\frac{x^3 - x - 6}{(x-3)(x^2-3)}$$
10. **Check if numerator can be factored:**
Try to factor $x^3 - x - 6$ by rational root theorem.
Test $x=2$:
$$2^3 - 2 - 6 = 8 - 2 - 6 = 0$$
So, $x=2$ is a root.
11. **Divide numerator by $(x-2)$:**
Using synthetic division:
$$x^3 - x - 6 \div (x-2) = x^2 + 2x + 3$$
12. **Rewrite numerator:**
$$x^3 - x - 6 = (x-2)(x^2 + 2x + 3)$$
13. **Final simplified form:**
$$\frac{(x-2)(x^2 + 2x + 3)}{(x-3)(x^2-3)}$$
This is the simplified form of the original expression.
