Complete answer: The given polynomial is 2 We need to find the degree of the above polynomial. In mathematics, an irreducible polynomial is, roughly speaking, a polynomial that cannot be factored into the product of two non-constant polynomials.The property of irreducibility depends on the nature of the coefficients that are accepted for the possible factors, that is, the field to which the coefficients of the polynomial and its possible factors are supposed to belong. Note that this expression is equivalent to having a negative exponent in the second term, since: This is not a polynomial, since we have a variable in the denominator of the expression. you can reduce some zero form loop and return.
