Polynomials
Lesson 9.1
OBJ: to add and subtract
polynomials.
Monomial


A number, variable, or the product of
a number and one or more variables
with whole number exponents.
Degree of a Monomial
• The sum of the exponents of the
variables in the monomial.
Polynomial


A monomial or a sum of monomials
(each called a term).
Degree of a Polynomial
• The greatest degree of its terms.
Leading Coefficient

The coefficient of the first term when
a polynomial is written so that the
exponents of a variable decrease
from left to right.
Different Polynomials




Monomial – a polynomial with only 1
term.
Binomial – a polynomial with 2
terms.
Trinomial – a polynomial with 3
terms.
All others are just referred to as
polynomials.
Adding Polynomials


Just like adding like terms; you only
add the coefficients.
You can add horizontally or vertically.
Subtracting Polynomials




Distribute the negative.
Drop the parentheses.
Combine like you would with addition
of polynomials.
Add subtract horizontally or
vertically.
