Am brand new to Mathematica, but would greatly value your help. Mathematica should be able to give exact roots to any polynomial of degree up to and including four and does so most of the time. However,, when I ask it for the exact solutions to, amongst other examples x^4-x-2=0 it insists on giving me numerical approximations to the equation, whether I use Solve or Reduce. It must be me, what am I doing wrong?
