👉 In mathematics, an irreducible polynomial is a polynomial that can be factored into a product of two or more linear factors. In other words, it cannot be written as a linear combination of smaller polynomials. For example: - The polynomial x^2 + 1 is not irreducible because it can be factored into (x+1)(x-1). - The polynomial 3x^2 - 4x + 5 is also not irreducible, since it cannot be
