Polynomials over the Rational Field Euclidean Ring
Irreducible Polynomial
Let D be a Euclidean ring, F its field of quotients. Prove the Gauss lemma for polynomials with coefficients in D factored as product of polynomials with coefficients in F.
Solution Summary
It is the explanation of the following problem:
Let D be a Euclidean ring, F its field of quotients. Prove the Gauss lemma for polynomials with coefficients in D factored as product of polynomials with coefficients in F.
The solution is given in detail.
Find thepolynomials that represent 1/x^3+x , x/x^3+x, x^2/x^3+x, and x^3/x^3+x modulo the irrreducible polynomial x^5+x^2+1 over F2 ( thefieldwith two elements 0 and 1)
Your answers should be polynomialsover F2 with degrees at most four. (Can you explain in here why at most degree four)
Note: Use the Eucliden algorith
Determine whether thepolynomials have multiple roots.

19. Let F be a field and let f(x) =...... The derivative, D(f(x)), of f(x) is defined by
D(f(x)) = ......
where, as usual, ....... (n times). Note that D(f(x)) is again a polynomial withcoefficients in F.
The polynomi
1. Prove that the polynomial x^4 - 16*(x^2) + 4 is irreducible in Q[x] (the ring of all polynomialswithrationalcoefficients).
2. Show that every element of C (i.e., every complex number) is algebraic over R (the ring of all real numbers).
Prove that in a Euclidean ring ( a , b ) can be found as follows
b = q0 a + r1 where d ( r1) < d (a )
a = q1 r1 + r2 where d ( r2) < d (r1 )
r1 = q1 r1 + r2 where d ( r3) < d ( r2 )
I need to do some research on the properties of palindromic polynomialswith Z(n) coefficients. I would like information/explanation of polynomialswith Z(n) coefficients. I would like to see examples of polynomialswith Z(1), Z(2), Z(3), Z(4), Z(5) and in general Z(n) coefficients. Also, I would like to see some examples of
Suppose F, E are fields and F is a subring of E. Suppose g is an element of E and is algebraic over F, that is p(g)=0 for some nonzero polynomial p(x) in F[x]. Then there must be a nonzero polynomial m(x) smallest degree among those nonzero polynomials in F[x] with g as a root. Prove m(x) cannot be factored as a(x)b(x) for poly
