Rewrite the equation in vertex form. y = x2 - 6x + 18
2 answers:
Complete square!
Vertex form is (x-h)^2+k
meaning that the vertex is located at (h,k).
3^2=9
vertex form, h=3, k=9, vertex is located at (3,9)

There was a suggestion to explain the completion of square as
x^2-6x=(x-3)^2-9.
However, this does not show where the (x-3) come from.
If this is a better explanation for any or all of you, here it is.
