1. **State the problem:** Simplify the expression $$\frac{8}{3v-6} + \frac{6v}{v+3}$$.
2. **Identify the denominators and factor if possible:**
- The first denominator is $$3v-6$$, which can be factored as $$3(v-2)$$.
- The second denominator is $$v+3$$, which is already factored.
3. **Rewrite the expression with factored denominators:**
$$\frac{8}{3(v-2)} + \frac{6v}{v+3}$$
4. **Find the least common denominator (LCD):**
The LCD is $$3(v-2)(v+3)$$.
5. **Rewrite each fraction with the LCD as denominator:**
$$\frac{8}{3(v-2)} = \frac{8(v+3)}{3(v-2)(v+3)}$$
$$\frac{6v}{v+3} = \frac{6v \cdot 3(v-2)}{3(v-2)(v+3)} = \frac{18v(v-2)}{3(v-2)(v+3)}$$
6. **Add the numerators over the common denominator:**
$$\frac{8(v+3) + 18v(v-2)}{3(v-2)(v+3)}$$
7. **Expand the numerators:**
$$8(v+3) = 8v + 24$$
$$18v(v-2) = 18v^2 - 36v$$
8. **Combine the numerator terms:**
$$8v + 24 + 18v^2 - 36v = 18v^2 - 28v + 24$$
9. **Write the full expression:**
$$\frac{18v^2 - 28v + 24}{3(v-2)(v+3)}$$
10. **Factor the numerator if possible:**
First, factor out the common factor 2:
$$2(9v^2 - 14v + 12)$$
Try to factor $$9v^2 - 14v + 12$$:
- The product of $$9 \times 12 = 108$$.
- We look for two numbers that multiply to 108 and add to -14, but no such integer pair exists.
Therefore, the numerator does not factor nicely over integers.
11. **Simplify the fraction by canceling common factors:**
The denominator has a factor 3, numerator has factor 2, no common factors to cancel.
12. **Final simplified expression:**
$$\frac{2(9v^2 - 14v + 12)}{3(v-2)(v+3)}$$
This is the simplest form.
**Answer:** $$\boxed{\frac{2(9v^2 - 14v + 12)}{3(v-2)(v+3)}}$$
