You could put it in vertex form by completing the square of the right side

I don't think we need to complete the square... \[y=(x+8)^2\]

Yep thats it you noticed (16/2)^2 is 64 so you didnt have to do anything So the vertex is (8,0)

how do you know that that is the vertex? What's the formula for finding a vertex?

Well when its in vertex form y=a(xh)^2+k (h,k) is the vertex in this case h is 8 and k is 0
