Q. Put the quadratic into vertex form and state the coordinates of the vertex.

\newline

y=x^{2}-12 x+20

\newline

Vertex Form:

y=

\newline

Vertex:

(\square, \square)

Identify Vertex Form: Identify the vertex form of a parabola. $\newline$ The vertex form of a parabola is $y = a(x - h)^2 + k$ , where $(h, k)$ is the vertex of the parabola.
Complete the Square: Complete the square to rewrite the quadratic equation in vertex form. $\newline$ Given equation: $y = x^2 - 12x + 20$ $\newline$ To complete the square, we need to find a value that makes $x^2 - 12x + \_\_\_$ a perfect square trinomial. $\newline$ The value needed is $(\frac{12}{2})^2 = 6^2 = 36$ .
Add and Subtract Values: Add and subtract the value found inside the equation. $\newline$ $y = x^2 - 12x + 36 - 36 + 20$ $\newline$ Now, we have added $36$ to complete the square, but we must also subtract $36$ to keep the equation balanced.
Rewrite Equation: Rewrite the equation with the perfect square trinomial and the constants combined. $\newline$ $y = (x^2 - 12x + 36) - 16$ $\newline$ $y = (x - 6)^2 - 16$ $\newline$ Now the equation is in vertex form.
Identify Parabola Vertex: Identify the vertex of the parabola. $\newline$ The vertex form of the equation is $y = (x - 6)^2 - 16$ . $\newline$ Comparing this with the vertex form $y = a(x - h)^2 + k$ , we find that $h = 6$ and $k = -16$ . $\newline$ Therefore, the vertex of the parabola is $(6, -16)$ .
