eheh you're doing it ALL wrong! the ti86 has a BUILT IN ROOT FINDER!!!!

first take the equation and make it into standard polynomial form..
ax^2+bx+c if it's more than that. that just make it to something like
that.. then.. press the 2ND POLY button.. put in the HIGHEST power
degree.. then put in the numbers.. then hit SOLVE.. and it'll give you
ALL the roots.

read the manual.. for the POLY  function..
