> x^4 + y^4 + A(x^2)  A(y^2) + 2(x^2)(y^2) >  B x y + C = 0 = F( x,y ) = F say.
A general procedure when x and y are in an implicit relationship is indicated:
Total differential of F gives
dy/dx =  del F,x / del F,y = 0 or del F,x = 0 ; It is the link relation between x and y.
It gives y = 2 x (A + 2 x^2)/ (B + 4 x^2) which should be plugged into F and solved. May be slightly cumbersome.
