It's already a square; we don't need to add anything to complete the square.

That's a vertex at x = -1. The corresponding y is y=0.
Answer: Vertex at (-1,0)
As for the other questions cut off there, the axis is the vertical line x = -1 and the range is y ≥ 0.
It is also a quadrilateral
X(x-7)=0
⇔x=0 or x-7=0
⇔x=0 or x=7
