# POLYNOMIALS AND RATIONAL EXPRESSIONS

Polynomial in standard form:

where n ≥ 0 is an integer and are constants
called the coefficients.

A polynomial with one term is called a monomial:
where k is a whole number. The monomials that form a poly-
nomial are called terms.

For a polynomial

Polynomial? Yes/No Coefficients Degree

Polynomials are added and subtracted by combining the mono -
mials that may differ only by coefficients.

Example: Perform the indicated operations

Multiplying Polynomials

Two polynomials are multiplied by using the Properties of Real
Numbers and Laws of Exponents .

Example:

Find the product:

Special Products

Evaluate: (2a + 3)(2a − 3) =

Factoring is the process of expressing a polynomial as a prod-
uct of two or more nontrivial polynomials.

Example:

A polynomial is called prime or irreducible if it cannot be
written as a product of two nontrivial polynomials.
