Solving an Unsolved Math Problem: Ring A & Polynomials

In summary, it is not possible for a ring A to have a polynomial of degree 2 equal to a polynomial of degree 4 in A[x]. This is because the formal definition of polynomial dictates that if p has degree 2 and q has degree 4, then p cannot be equal to q. However, if p and q determine the same polynomial function, then the answer is affirmative. For example, in the ring $\mathbb{Z}_2[x]$, the polynomials $p(x)=x^2$ and $q(x)=x^4$ can be equal.

I quote an unsolved problem posted in another forum on December 5th, 2012.

Is there any ring A such that in A[x] some polynomial of degree 2 is equal to a polynomial of degree 4? Can you give me an example and explain how this could be true. Thanks in advance!

It is not possible. According to the formal definition of polynomial, if $p$ has degrre $2$ and $q$ degrre 4 then

$$p=(a_0,a_1,a_2,0,\ldots,0,\ldots)\qquad (a_2\neq 0)\\ q=(b_0,b_1,b_2,b_3,b_4,0,\ldots,0,\ldots)\quad (b_4\neq 0)$$

so, $p\neq q$. Another thing is that if $p$ and $q$ can determine the same polynomical function, and the answer is affirmative. For example, choose in $\mathbb{Z}_2[x]$ the polynomials $p(x)=x^2$ and $q(x)=x^4$.
 

FAQ: Solving an Unsolved Math Problem: Ring A & Polynomials

What is the "Ring A" and how does it relate to solving unsolved math problems?

The "Ring A" is a mathematical concept that refers to a set of numbers or elements that follow specific rules of addition and multiplication.
