Simplify



 3x(9x^2+3xy^2+y^4)-y^2(9x^2+3xy^2+y^4)  Distributive Property



 3x(9x^2) + 3x(3xy^2) - 3x(y^2) - [y^2(9x^2) + y^2(3xy^2) + y^4(y^4)]

 

 27x^3 + 9x^2y^2 - 3xy^2 - (9x^2y^2 + 3xy^4 + y^8)

 

 27x^3 + 9x^2y^2 - 3xy^2 - 1(9x^2y^2 + 3xy^4 + y^8)



 27x^3 + 9x^2y^2 - 3xy^2 - 9x^2y^2 - 3xy^4 - y^8



 27x^3 + 9x^2y^2 - 3xy^2 - 9x^2y^2 - 3xy^4 - y^8  combine 



 27x^3 - 3xy^2 - 3xy^4 - y^8
