Definitely! And I won't even believe the output...

I want to solve polynomial equations and in order to do so, I do
something like:
sage: R. = PolynomialRing(QQ, order='lex')
sage: I = R.ideal([x*y-1, x^2-y^2])
sage: I.groebner_basis()
[x - y^3, y^4 - 1]
Now I have to take the equation with only one variable, find the
solutions for it (over so QQ
