roots to 4th, 5th, 6th & 7th degree polynomials

The best I can promise is all denominators are nonzero, and dimensional
analysis passes.

See if you can understand the concept. If it works, it can find the roots
to any degree polynomial. If it doesn't, then at best it may give a rough
estimate.

I'm wondering... Do you think that your algorithm can find the roots of a
polynomial like

p(x) = x^4 - 4x^3 + 6x^2 - 4x + 1 ?

This is an easy one : it has only one root (x=1) of multiplicity 4. And
since p(x) >= 0, i can't see how your algorithm would apply here.
