Numerical methods exist for solving polynomials of higher degrees.  Most require
an approximate value to begin and work best when you are not near a max or min
point (since slope is used and slopes near 0 will send you far from your
original guess / approximation).  Assuming you want the solution more than the
process, the TI-graphing calculators can be used with a SOLVE button.  Enter
the polynomial, find a solution at a nearby x-intercept, and ask for a
solution.  It will numerically approximate each one for you.

DO YOU HAVE A WAY INFO ON NUMERICALLY
