SUMMARY
Every non-constant polynomial over a field F can be expressed as a product of irreducible polynomials. This conclusion is supported by the definition of irreducibility, where a polynomial is irreducible if it cannot be factored into the product of two non-constant polynomials. For instance, the polynomial x² - a² can be factored into (x - a)(x + a), demonstrating that it is a product of two first-degree irreducible polynomials. The degree of the irreducible factors must sum to the degree of the original polynomial.
