You forgot that the vertex can be shifted to any point (h,k):
y-k = (x-h)2 /(4p)

It can of course be written other ways:
y-k = a(x-h)2
y = ax2 +bx +c
In the latter case, you can find the vertex using h=-b/(2a) and k=c-ah2


By the way, you might want to avoid arguing with your girlfriend in 'public' : )
