(x8 + x4y4 + y8)
x8 + 2 x4 y4 + y8 - x4 y4
(x4 + y4)2 - ( x2 y2)2
(x4 + y4 + x2 y2)( x4 + y4 - x2 y2)
[(x2 y2)2 - (xy)2] )( x4 + y4 - x2 y2)
(x2 + x y + y2)( x2 - x y + y2) )( x4 + y4 - x2 y2)
x8 + 2 x4 y4 + y8 - x4 y4
(x4 + y4)2 - ( x2 y2)2
(x4 + y4 + x2 y2)( x4 + y4 - x2 y2)
[(x2 y2)2 - (xy)2] )( x4 + y4 - x2 y2)
(x2 + x y + y2)( x2 - x y + y2) )( x4 + y4 - x2 y2)
