So, what is a POLYNOMIAL?
It is an equation made up of MONOMIALS (mono meaning ONE real number, variable, or a product of each).
Each TERM of a polynomial is called a monomial.
A polynomial made up of one term is a MONOMIAL. Ex: 4x2
A polynomial made up of two terms is a BINOMIAL. Ex: 4x + 7
Anything more than two terms simply has the name POLYNOMIAL.

The largest exponent of any term is the DEGREE of the polynomial.
This polynomial is in STANDARD FORM since their terms are in descending order by degree.

Write each polynomial in standard form.
Then classify it by degree and by number of terms.
1. ­7x + 5x4
2. x2 ­ 4x + 3x3 + 2x
3. 4x ­ 6x + 5
4. 3x3 + x2 ­4x + 2x3
5. 6 ­ 2x5
