(x^6-y^6)^2[(x^6+y^6)-x^3y^3]^2[(x^6+y^6)+x^3y^3]^2
=(x^6-y^6)^2[(x^6+y^6)^2-x^6y^6]^2
=(x^6-y^6)^2(x^12+y^12+x^6y^6)^2
=(x^18-y^6x^12+x^6y^12-y^18+x^12y^6-x^6y^12)^2
=(x^18-y^18)^2
=x^36-2x^18y^18+y^36
=(x^6-y^6)^2[(x^6+y^6)^2-x^6y^6]^2
=(x^6-y^6)^2(x^12+y^12+x^6y^6)^2
=(x^18-y^6x^12+x^6y^12-y^18+x^12y^6-x^6y^12)^2
=(x^18-y^18)^2
=x^36-2x^18y^18+y^36
