```Molly,

You are probably obtaining Root objects. These are a somewhat arcane, but
exact representation of the roots of a polynomial equation. To find out more
about them, and how to convert them to regular numbers, type the following
and evaluate:

?*Root*

Especially look at Root, and follow the links at the end of the usage
messages to the Function Help pages.
