Talk:Discrete Mathematics/Finite fields

Who is the designer of this page because you have a multiplication error.

If you go down the page to the section:



then to the line:

"So then(a+bx)(c+dx)=ac+bdx2+ad+bc "

This line should read: ... + (ad+bc)x

m(x) has several roots
Hi!

You say <=F(α) where α is "the root of" m(x) - we define α to be the root of m(x).>>

I think we are talking about a finite field F (although, I believe, this fact isn't stated in the page and I think it would be good if it were). Nevertheless, the polynomial m(x) has several roots, so a commentary stating the isomorphism of F(α) for every root α of m(x) may be useful. In fact, if F isn't finite, then the F(α) can be distinct! (We can take for example x^3-2 over Q). I would add my last comment as well, for completeness!
