Comment (by kcrisman):
The suggestion was made there that Sympy might be better at this. Is it?
At least here it is giving answers - I don't think any are erroneous or
missing, but I didn't check very hard, either.
{{{
sage: from sympy import solve as ssolve
sage: ssolve(x-sqrt(x),x)
[1, 0]
sage: ssolve(x^2-sqrt(x),x)
[1, 0]
sage: ssolve(x^2+sqrt(x),x)
[-1/2 + 3**(1/2)*I/2, -1/2 - 3**(1/2)*I/2, 0]
sage: ssolve(a*x^2+sqrt(x),x)
[(-1/a)**(2/3),
0,
(-1/a)**(2/3)*(-1 - 3**(1/2)*I)/2,
(-1/a)**(2/3)*(-1 + 3**(1/2)*I)/2]
}}}
Does anyone know whether sympy's solve capabilities is a strict superset
of Maxima's? I assume not.
