Factor Complete Square
1. The problem is to analyze and simplify the quadratic expression $$-4x^2 + 24x - 4$$.
2. First, factor out the greatest common factor from all terms, which is $$-4$$.
3. Factoring out $$-4$$ gives:
$$-4(x^2 - 6x + 1)$$
4. Next, complete the square inside the parentheses to express the quadratic in vertex form.
5. Complete the square for $$x^2 - 6x + 1$$:
Add and subtract $$\left(\frac{6}{2}\right)^2 = 9$$ inside the parentheses:
$$x^2 - 6x + 9 - 9 + 1 = (x - 3)^2 - 8$$
6. Substitute back:
$$-4((x - 3)^2 - 8)$$
7. Distribute the $$-4$$:
$$-4(x - 3)^2 + 32$$
8. This is the vertex form of the quadratic, where the vertex is at $$(3, 32)$$.
9. This shows the quadratic opens downward (since the coefficient of the squared term is negative) and has a maximum point at the vertex.
Final answer: $$-4(x - 3)^2 + 32$$
