If your expressions are tame enough, you can do this by calling expand() and collect() repeatedly on your expression. If you have mixed terms (say, x1,x2 appear in the same term and you have a preference for which one to factor) you can hack it together with repeated factorings and subtractions. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
