The monomials that make up a polynomial are called the ____________ of the polynomial.
In the polynomial , the monomials 2x and x can be combined because they are ____________________. The result is .
The polynomial is a _______________ because it has 3 unlike terms.
A polynomial such as is a _______________ because it has 2 unlike terms.
The degree of a polynomial is the degree of the monomial with the greatest degree. For example, the degree of is 2 and the degree of is 3.

Standard Form - A polynomial is written in standard form when
• the terms are arranged by degree in descending number order• all coefficients are real numbers• all exponents are non-negative integers
Using the example
In standard form this would be written as
The leading term is _______
The leading coefficient is ________
The degree is ________
