Question: top-center: fraction expression with numerator $-4x^3 (2x + 2) - 2x^2 (4x + 4)$ and denominator $2x^2$ appearing near the upper center of the image.
1. **State the problem:** Simplify the expression $$\frac{-4x^3 (2x + 2) - 2x^2 (4x + 4)}{2x^2}$$. 2. **Expand the numerator:** $$-4x^3 (2x + 2) = -4x^3 \cdot 2x - 4x^3 \cdot 2 = -8x^4 - 8x^3$$ $$-2x^2 (4x + 4) = -2x^2 \cdot 4x - 2x^2 \cdot 4 = -8x^3 - 8x^2$$ 3. **Combine the expanded terms:** $$-8x^4 - 8x^3 - 8x^3 - 8x^2 = -8x^4 - 16x^3 - 8x^2$$ 4. **Rewrite the expression:** $$\frac{-8x^4 - 16x^3 - 8x^2}{2x^2}$$ 5. **Factor the numerator:** $$-8x^2 (x^2 + 2x + 1)$$ 6. **Rewrite the expression with factored numerator:** $$\frac{-8x^2 (x^2 + 2x + 1)}{2x^2}$$ 7. **Cancel common factors:** $$\frac{\cancel{-8x^2} (x^2 + 2x + 1)}{\cancel{2x^2}} = -4 (x^2 + 2x + 1)$$ 8. **Recognize perfect square:** $$x^2 + 2x + 1 = (x + 1)^2$$ 9. **Final simplified expression:** $$-4 (x + 1)^2$$
