[Axiom-mail] Factorizing an expression

[Ludovic Courtès]

Hi,

I'm looking for a way to turn an expression into a factor of another
one.  For instance, given this equation:

  (a/b)^2 + (a/b)y + 3(a/b)x

tell Axiom to somehow turn this into:

  (a/b).((a/b) + y + 3x)

Apologize if this is answered elsewhere but I couldn't find it in the
book.

Thanks,
Ludovic.
