I would like to be able to manipulate the formulae for the
4 roots to a quartic equation (and likewise, the 3 roots
to a cubic equation) rather than just see the formulae
displayed. Is there any way of doing this, short of
copying these 4-page formulae down by hand and reentering
them into Mathematica? I am sure to make mistakes that
way (I've tried it and given up halfway into the formulae).
Thank you & thank you, WRI.
