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.
