1. **State the problem:** Solve the fractional equation $$\frac{2x}{x-3} + \frac{4}{x+2} = \frac{10}{x^2 - x - 6}$$.
2. **Factor the denominator on the right side:** Note that $$x^2 - x - 6 = (x-3)(x+2)$$.
3. **Rewrite the equation with factored denominator:**
$$\frac{2x}{x-3} + \frac{4}{x+2} = \frac{10}{(x-3)(x+2)}$$
4. **Find the least common denominator (LCD):** The LCD is $$(x-3)(x+2)$$.
5. **Multiply both sides of the equation by the LCD to clear denominators:**
$$\left(\frac{2x}{x-3} + \frac{4}{x+2}\right)(x-3)(x+2) = \frac{10}{(x-3)(x+2)}(x-3)(x+2)$$
6. **Simplify each term:**
- $$\frac{2x}{x-3} \times (x-3)(x+2) = 2x(x+2)$$
- $$\frac{4}{x+2} \times (x-3)(x+2) = 4(x-3)$$
- Right side simplifies to $$10$$
7. **Write the simplified equation:**
$$2x(x+2) + 4(x-3) = 10$$
8. **Expand the terms:**
$$2x^2 + 4x + 4x - 12 = 10$$
9. **Combine like terms:**
$$2x^2 + 8x - 12 = 10$$
10. **Bring all terms to one side:**
$$2x^2 + 8x - 12 - 10 = 0$$
$$2x^2 + 8x - 22 = 0$$
11. **Divide the entire equation by 2 to simplify:**
$$x^2 + 4x - 11 = 0$$
12. **Use the quadratic formula to solve for $x$:**
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$ where $a=1$, $b=4$, $c=-11$.
13. **Calculate the discriminant:**
$$\Delta = 4^2 - 4 \times 1 \times (-11) = 16 + 44 = 60$$
14. **Find the roots:**
$$x = \frac{-4 \pm \sqrt{60}}{2} = \frac{-4 \pm 2\sqrt{15}}{2} = -2 \pm \sqrt{15}$$
15. **Check for restrictions:** The denominators cannot be zero, so $x \neq 3$ and $x \neq -2$.
16. **Final solution:**
$$x = -2 + \sqrt{15} \quad \text{or} \quad x = -2 - \sqrt{15}$$
Both values do not equal 3 or -2, so both are valid.
**Answer:** $$x = -2 \pm \sqrt{15}$$
