canonical form

[retoa]

Hello,

I am trying to use the"canonical_form" function from the catalog, in CAS mode.
According to the help it should act as in this example:

canonical_form(2*x^2-12*x+1) -> 2*(x-3)^2-17

on the emulator it works like expected, on the real prime it does this:

canonical_form(2*x^2-12*x+1) -> 2*x^2-12*x+1

Actually the canonical form should be 2*x^2-12*x+1, 2*(x-3)^2-17 is the vertex form as (3,-17) is the vertex. So I don't know what should be the intended behaviour, but a function that returns 2*x^2-12*x+1 is not very useful, it only simplifies the expression.

So how can I find 2*(x-3)^2-17 starting from 2*x^2-12*x+1 on the real Prime?

Thank you very much for the help.
