x^2*y^2*((18*x^2-12*x^3*y^4+6*x^2*y^2)/6) = 0
(x^2*y^2*(18*x^2-12*x^3*y^4+6*x^2*y^2))/6 = 0
( 18*x^2-12*x^3*y^4+6*x^2*y^2 )
18*x^2-12*x^3*y^4+6*x^2*y^2 = 0
6*x^2*(y^2-2*x*y^4+3) = 0
y^2-2*x*y^4+3 = 0 // - y^2+3
-2*x*y^4 = -(y^2+3) // : -2*y^4
x = (-(y^2+3))/(-2*y^4)
x = (1/2)*y^-4*(y^2+3)
6*x^2 = 0
6*x^2 = 0 // : 6
x^2 = 0
x = 0
