There is only one solution (an ellipse). If you treat each point on the ellipse as a different solution there is no ordering of them. Or did you mean the first points that occur to you, which are probably (1,0) and (-1,0)?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2433841880619171855.post-81633430345775368172011-03-01T16:58:31.537+00:002011-03-01T16:58:31.537+00:00What do you mean "first two solutions"? ...What do you mean "first two solutions"?
