HP50g: How to display repeated roots and simplifying answers

[Fanboy]

Hi, I was using my 50g to solve for higher degree polynomials and I noticed that the 50G omits displaying roots which are repeated. Example: m^5 + 5m^4 -2m^3 -10m^2 +m +5 = 0
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.

Also, I was wondering about the simplification functions built in to the 50g. I'm also using the 50g for solving integrals and I often get a huge mess of an answer (which can be simplified). The 'simplify' function doesn't really work in most cases for me. Can I simplify an expression with multiple natural logs or is this a limitation of the calculator?
