 ..........complete squares
-> and  , so the center is at ( ,  )
semi-major axis length:
 ≈ 
semi-minor axis length: ≈
foci: ( ,  ) =( , ) ≈ ( , )
and
foci :( , ) =( , ) ≈ ( ,)
vertices:
The vertices are  units above and below the center, at
( , ) ≈ ( , )
and
( , ) ≈ ( , )
The co-vertices are  units to either side of the center, at
( , ) and ( , )
