Factoring polynomials on 85

There is a way to do this, without any programs. But you must have
exactly 1 variable.


Say you want 2x^2-x+1


Press POLY
Then type in the order of the polynomial, 2
Then type in the 3 coefficents: 2,-1,1
It will give you two answers. These are the answers to 2x^2-x+1=0. But
you can reverse them and turn them into factors.


I'm too lazy to do the work, so I'm making up these numbers, but say the
calc returns 3 and 5. The factors would be (x-3)(x-5).
