Polynomials in Several Variables

A polynomial in two variables, x and y, contains the sum of one or more monomials in the form ax n y m. The constant a is the coefficient. The exponents n and m represent whole numbers. The degree of a polynomial in two variables is the highest degree of all its terms.
