RULESRULES If a term in a polynomial has one variable as a If a term in a polynomial has one variable as a
factor, then the degrees of that term is the factor, then the degrees of that term is the power of the variable.power of the variable.
If two or more variables are present in term as a factor, the degree of the term is the sum of the power of the variables.
The degree of a polynomial is the greatest degree of any term in a polynomial.
Any non-zero constant is defined to be a polynomial of degree zero.
