is the distance from the center to either of the foci. Since the foci are equidistant from the -axis and the -coordinates of the foci are both , we can conclude that the center of the ellipse is the origin, (0,0). Given that you should be able to determine the distance from the center to either focus by inspection and square that value to get .
