You have to look deep to see what is going on ;
in analytical geometry , r the the equation axe+2hxy+2gx+2fy+c =0 represents an ellipse when ab>h2 ; if the centre of the curve be the origin, the equation is 1 x 2 +2h=1 xy +b i y 2 = c1 , and if addition a pair of conjugate diameters are the axes , the equation is further simplified form is x 2 / a 2 +y2 /b2 = 1 , in which the centre is the origin and the major and minor axes the axes of co-ordinates.
so if you think about this you can see the problem .
