Hi. This is not a simplification, per se, but this could get you
closer:
sage: var('y,z')
(y, z)
sage: F = 3*x^2*y*z + x*y*z + y*z == 0
sage: F.factor()
(3*x^2 + x + 1)*y*z
It also is smart enough to do this:
sage: F.solve(x)
[x == -1/6*I*sqrt(11) - 1/6, x == 1/6*I*sqrt(11) - 1/6]
sage: solve(F,y)
[y == 0]
sage: solve(F,z)
[z == 0]
I can't see anything immediate in Maxima that would automatically
simply omit the y and z, though.
