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
Adding and Subtracting Polynomials
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) =
Evaluate:
Evaluate:
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.
