1. **State the problem:** Simplify the algebraic expression $$\frac{2}{x-2} + \frac{3}{x^3 - 4x}$$.
2. **Factor the denominator:** Notice that $$x^3 - 4x$$ can be factored by taking out the common factor $$x$$:
$$x^3 - 4x = x(x^2 - 4)$$.
3. **Further factor the quadratic:** Recognize $$x^2 - 4$$ as a difference of squares:
$$x^2 - 4 = (x-2)(x+2)$$.
4. **Rewrite the expression:** Substitute the factored form back:
$$\frac{2}{x-2} + \frac{3}{x(x-2)(x+2)}$$.
5. **Find the common denominator:** The least common denominator (LCD) is $$x(x-2)(x+2)$$.
6. **Rewrite each fraction with the LCD:**
$$\frac{2}{x-2} = \frac{2 \cdot x(x+2)}{x(x-2)(x+2)} = \frac{2x(x+2)}{x(x-2)(x+2)}$$
7. **Add the fractions:**
$$\frac{2x(x+2)}{x(x-2)(x+2)} + \frac{3}{x(x-2)(x+2)} = \frac{2x(x+2) + 3}{x(x-2)(x+2)}$$
8. **Expand the numerator:**
$$2x(x+2) + 3 = 2x^2 + 4x + 3$$
9. **Check if numerator can be factored:** The quadratic $$2x^2 + 4x + 3$$ does not factor nicely with integer factors.
10. **Final simplified expression:**
$$\boxed{\frac{2x^2 + 4x + 3}{x(x-2)(x+2)}}$$
