HP50g: How to display repeated roots and simplifying answers

The calculator only gives 3 answers instead of all 5. Can I change this? It's important that I see all the roots. Mt Ti 84 already does this but it can't give exact answers which is why I'm using the 50g.

As Joe pointed out, FACTORS is what you're looking for to give exact roots.

Just in case you were not aware of it, you can find the 5 roots numerically using PROOT. Unlike the 84+ PolySmlt2 APP, PROOT can accept complex coefficients.
