Mon, 1/30SWBAT…add, subtract polynomials and multiply a monomial by a polynomial
Agenda 1. Class results (5 min)2. Vocabulary (10 min)3. Adding and subtracting polynomials (7.5 min)4. Multiplying a monomial with a polynomial (7.5 min)5. Solving equations with polynomials (10 min)6. Exit slip (5 min)
Warm-Up:1. Read the weekly agenda, including the
reminders!2. Set up your notes. Topic = Polynomials
HW#1: Polynomials
We are starting a new unit: Polynomials, Quadratic Equations, and Quadratic Functions
SWBAT…1. Add, subtract, and multiply polynomials (today)2. Solve multi-step equations with polynomials (today)3. Multiply two binomials – FOIL (tomorrow)4. Factor polynomials 5. Solve quadratic equations by factoring6. Solve quadratic equations by the Quadratic Formula7. Graph quadratic functions
1. Vertex2. Axis of symmetry3. x-intercept4. y-intercept
Daily warm-ups, almost daily exit slips, daily HW, weekly quizzes, test the first week of March.
A term is either a single number or a variable, or numbers and variables multiplied together.
A monomial is one term A binomial is the sum or difference of two monomials A trinomial is the sum or difference of three monomials A polynomial is a monomial or the sum or difference of
monomials (not division)
Expression Is it a polynomial?Why?
Monomial, binomial, or trinomial?

Expression Is it a polynomial?Why?
Monomial, binomial, or trinomial?
4y – 5xz Yes; 4y – 5xz is the difference of two monomials.
Binomial
-6.5
6x3 + 4x + x + 3
Expression Is it a polynomial? Monomial, binomial, or trinomial?
4y – 5xz Yes; 4y – 5xz is the difference of two monomials.
Binomial
-6.5 Yes; -6.5 is a constant Monomial
6x3 + 4x + x + 3
Expression Is it a polynomial? Monomial, binomial, or trinomial?
4y – 5xz Yes; 4y – 5xz is the difference of two monomials.
Binomial
-6.5 Yes; -6.5 is a constant Monomial
6x3 + 4x + x + 3
Expression Is it a polynomial? Monomial, binomial, or trinomial?
4y – 5xz Yes; 4y – 5xz is the difference of two monomials.
Binomial
-6.5 Yes; -6.5 is a constant Monomial
6x3 + 4x + x + 3 Yes; 6x3 + 4x + x + 3 = 6x3 + 5x + 3, the sum of three monomials
Trinomials
Degree of a monomial The degree of a monomial is the sum of the
exponents of all its variables.Ex1: 3a2b3
Degree = 2 + 3 = 5Ex2: xy2z7
Degree = 1 + 2 + 7 = 10Ex3: 7Degree = 0 A constant has degree 0.
Degree of a polynomial The degree of a polynomial is the greatest degree
of any term in the polynomial.Ex. 2d3 – 5c5d – 7Step 1: Find the degree of each term2d3: Degree = 35c5d: Degree = 5 + 1 = 67: Degree = 0Step 2: The degree of the polynomial is the greatest
degree, 6.
