I see that Axiom produces different representations for the roots of
polynomials in the form of lists, but I do not find the operations that
relates the corresponding elements of these lists.
As a concrete example, in a follow-up of the example that I have posted a few
weeks
ago, consider the lists produced by:
allRootsOf(p^3 - p + 1/10)$RECLOS(FRAC INT)
[%F8,%F9,%F10]
solve((p^3 - p + 1/10=0)::EQ EXPR INT,p)
+-----------+ +-----------+
| 2 | 2
\|- 3%p0 + 4 - %p0 - \|- 3%p0 + 4 - %p0
[p= %p0,p= --------------------,p= ----------------------]
2 2
Type: List Equation Expression Integer
radicalSolve(p^3 - p + 1/10=0,p)
+------------------+2
| +-+ +-----+
+---+ |- 3\|3 + \|- 373
(- 3\|- 3 + 3) |------------------ - 2
3| +-+
\| 60\|3
[p= -----------------------------------------,

| +-+ +-----+

p= -----------------------------------------,

So, I mean eg a command that takes %F8 as input and gives as output the
correspondig equation (or rhs) in the second or third list.
Is there such command?
