1. **State the problem:** Simplify the expression $X - 2 (x + 2) - 2 (x - 2)(x - 2)$.
2. **Rewrite the expression:**
$$X - 2(x + 2) - 2(x - 2)^2$$
3. **Expand the terms:**
- Expand $-2(x + 2)$:
$$-2 \times x - 2 \times 2 = -2x - 4$$
- Expand $(x - 2)^2$ using the formula $(a - b)^2 = a^2 - 2ab + b^2$:
$$x^2 - 2 \times x \times 2 + 2^2 = x^2 - 4x + 4$$
- Multiply by $-2$:
$$-2(x^2 - 4x + 4) = -2x^2 + 8x - 8$$
4. **Substitute expansions back:**
$$X - 2x - 4 - 2x^2 + 8x - 8$$
5. **Combine like terms:**
- Combine $X$ and $-2x$ and $8x$:
$$X + (-2x + 8x) = X + 6x$$
- Combine constants $-4$ and $-8$:
$$-4 - 8 = -12$$
6. **Final simplified expression:**
$$-2x^2 + X + 6x - 12$$
**Answer:**
$$\boxed{-2x^2 + X + 6x - 12}$$
