In Response To 'Re: Re: Polynomial factorization by roots?'  As a side note, I tried this out on my HP50g.
When I entered X^4+2*X^2+1 and pressed "FACTOR" I got the answer (X+i)^2*(Xi)^2
pressing "COLLECT" for the same polynomial I got the answer (X^2 + 1)^2
I tried it on the polynomial X^33*X^22*X+6
FACTOR > (X3)*(X+SQRT[2])*(XSQRT[2])
COLLECT > (X3)*(X^22)
The HP50g also beats the pants off of Mathematica in unit management.
