hp 50 g simplify solutions

[peacecalc]

Hello all,

@Marcus: well it is a possibility and I get indeed a shorten expression (I tried it of course). But it has its limits it stops with nested roots ... and no further simplyfication was possible.

@Gilles: this simple case is of course solveable with the means of the hp 50g. It is a pity, that the general program (polyroot) isn't able to give the simple answers for the simple cases of equations. I tried your suggestion: simplification "by parts", too. But I failed with this approach. I even don't see what the pattern which is the obstacle for simplyfication (of course it seems to be the nested roots and nroots, but nothing more specific).

@Brad: please have a look to the answer @Gilles.
