Ouch, and I thought I had accomplished a lot in the 5 minutes I had available. Of course the negative sign doesn't work with even multiplicity. So I guess having -1 1 at the beginning is the only real solution.

How about { -2 1 2 1 3 2 5 1 }? I.e. extract just one power of the first factor and make it negative. This would only need to be done if there is an even power of the first factor.
