Affine plane algebraic curves

...For an irreducible polynomial f (x,y) , such as x2 ( x +1 )-y2 0 or x4 y4-2x ( x2 y2 )=0, the set of points ( x , y ) such that f ( x , y )=0 is a plane algebraic curve (affine plane algebraic curve). When the degree of f ( x , y ) is n , it is called an n -th degree curve. ...
