Every polynomial over a field F may be factored into a product of a non-zero constant and a finite number of irreducible (over F) polynomials. This decomposition is unique up to the order of the factors and the multiplication of the factors by non-zero constants whose product is 1. Over a unique factorization domain the same theorem is true, but is more accurately formulated by using the notion of primitive polynomial. A primitive polynomial is a polynomial over a unique fact… WebThe only irreducible polynomials are those of degree one [ edit] The field F is algebraically closed if and only if the only irreducible polynomials in the polynomial ring F [ x] are those of degree one. The assertion "the polynomials of degree …
WebJun 29, 2015 · An irreducible polynomial can't be divided by anything except for associates (i.e. unit multiples) of itself and 1. In particular, no polynomial can be divided by a polynomial of higher degree (you'd get a rational function). Your concept of division seems backwards.
Web1. The given polynomial is in fact not irreducible. There is at least one decomposition: $$ (x^2+x+1)\cdot (x^5+x^4+x^3+x+1) = x^7+x^5+1 $$.
