To factor a polynomial completely the process is similar to prime factorization of integers. A polynomial is said to be prime if it cannot be expressed as a product of other polynomials. Completely factored polynomial is written as a product of monomial factors and prime polynomials having at least two terms. Taking polynomial for example, $x^{4}$ + 4$x^{3}$ + 6$x^{2}$ + 4 x + 1 complete factors = (x + 1) (x + 1) (x + 1) (x + 1)

For example $x^{4}$ + 4$x^{3}$ + 6$x^{2}$ + 4 x + 1 complete factors = (x + 1) (x + 1) (x + 1) (x + 1) There is no further factorisation
