Extract solutions from solve
I am new to sage. So, sorry if my question is trivial.
How can I get the values of a solve operation. Say I have
x = var('x'); f = x^2 - 5*x + 6; z = solve(f = 0, x); show(z);
gives me something like
[x == 2, x == 3]
How can I take the value 2 or 3 from that?
Also, when I was trying to solve another equation (quiet a long one), I get the solution as
[0 = something something.....]
What does that zero mean?
