The highest power of the variable in a polynomial is called the degree of the polynomial. A polynomial whose degree is one is called a linear polynomial. A polynomial whose degree is two is called a quadratic polynomial.The expression which contains one or more terms with non-zero coefficient is known as a polynomial. The highest power in a univariate polynomial is called its order, or in some cases its degree.
