I did the following and only got 3/2 as an answer, instead of getting 3/2 & 8, as an answer:

ans=solve(2*x^2-19*x+24==0,x)
x0=ans[0].rhs()
show(x0)

Doing, factor(2x^2-19x+24), displays, (x - 8)(2x - 3).

If you print ans, you will see that the result of solve is:

[x == (3/2),x == 8]

When you do ans[0].rhs(), you are grabbing the right hand side of the first statement. To get the second one, do ans[1].rhs().
