comment Find roots of polynomial with degree $\ge 5$
Since you say "there are only terms of even degree", do you mean the polynomials are of the form $\sum_{i=0}^n a_i x^{2i}$? In that case, would it help to substitute $y = x^2$ and solve the corresponding polynomials $\sum_{i=0}^n a_i y^i$?

comment Why does X divided by zero not equal X?
I'm sorry, but your analogy makes little sense. Multiplication, division and zero are well-defined mathematical concepts that you cannot simply discuss away or re-interpret as you like.
