1. **State the problem:** Find the limit $$\lim_{x \to 3} \frac{\ln(x-2)}{2x^2 - 6x}$$.
2. **Recall the formula and rules:** We are dealing with a limit of a fraction where the numerator is a natural logarithm function and the denominator is a quadratic expression. If direct substitution leads to an indeterminate form like $$\frac{0}{0}$$, we can apply L'Hôpital's Rule.
3. **Evaluate the limit by direct substitution:** Substitute $$x=3$$:
$$\ln(3-2) = \ln(1) = 0$$
$$2(3)^2 - 6(3) = 18 - 18 = 0$$
So the limit is of the form $$\frac{0}{0}$$, which is indeterminate.
4. **Apply L'Hôpital's Rule:** Differentiate numerator and denominator separately:
- Numerator derivative: $$\frac{d}{dx} \ln(x-2) = \frac{1}{x-2}$$
- Denominator derivative: $$\frac{d}{dx} (2x^2 - 6x) = 4x - 6$$
5. **Evaluate the new limit:**
$$\lim_{x \to 3} \frac{1/(x-2)}{4x - 6} = \lim_{x \to 3} \frac{1}{(x-2)(4x - 6)}$$
Substitute $$x=3$$:
$$\frac{1}{(3-2)(4(3) - 6)} = \frac{1}{1 \times (12 - 6)} = \frac{1}{6}$$
6. **Final answer:**
$$\boxed{\frac{1}{6}}$$
