Sum of monomials.

- The highest degree of the monomials determines the degree of the polynomial.
- When all the monomials have the same degree, it is a
**homogeneous polynomial**. - A monomial is a polynomial with one term.
- A polynomial can have several variables.

### Examples

- The polynomial 5
*x*² + 2*x*− 12 is a polynomial of degree 2. This polynomial is not homogeneous. - The polynomial 2
*x*^{2}*y*^{5}+ 4*xy*^{6}− 7*x*^{3}*y*^{4}is a homogeneous polynomial of degree 7. The sum of the exponents of the variables in each monomial is 7.
