Goal We can add, subtract, multiply and divide these polynomials. Today we are going to focus on how to MULTIPLY BINOMIALS.
What is FOIL The FOIL method is ONLY used when you multiply 2 binomials. It is an acronym that tells you which terms to multiply.
FOIL F - first O - outside I - inside L - last
Example 1 Use the FOIL method to multiply the following binomials: (y + 3)(y + 7)
(y + 3)(y + 7). F tells you to multiply the FIRST terms of each binomial. y2y2
(y + 3)(y + 7). O tells you to multiply the OUTER terms of each binomial. y 2 + 7y
(y + 3)(y + 7). I tells you to multiply the INNER terms of each binomial. y 2 + 7y + 3y
(y + 3)(y + 7). L tells you to multiply the LAST terms of each binomial. y 2 + 7y + 3y + 21 Combine like terms. y 2 + 10y + 21
Example 3 (2a – 3b)(2a + 4b) Answer: 4a 2 + 2ab – 12b 2
Example 4: You try
Example 5: You try

Homework FOIL Puzzle
Objective: To be able to find the product of two binomials. Objective: To be able to find the product of two binomials. 8.7 Multiplying Polynomials Part.
Multiplication of Polynomials. Use the Distributive Property when indicated. Remember: when multiplying 2 powers that have like bases, we ADD their.
PreTest Chapter 4. Leave your answer in exponent form. 1.(3 6 )(3 4 ) Product Rule.
5.4 Factoring Polynomials Group factoring Special Cases Simplify Quotients.
Chapter 6 – Polynomials and Polynomial Functions
Polynomials. The Degree of ax n If a does not equal 0, the degree of ax n is n. The degree of a nonzero constant is 0. The constant 0 has no defined degree.
We use the acronym below to multiply two binomials. F – O – I – L – FIRST OUTSIDE INSIDE LAST.
© William James Calhoun, : Multiplying Polynomials OBJECTIVES: The student will (1) use the FOIL method to multiply two binomials, and (2) multiply.
How do I use Special Product Patterns to Multiply Polynomials?
I can show multiplying polynomials with the FOIL. OBJECTIVE.
Warm Up Simplify each expression: 1.(-4) (5x) 2 5x 1 4.-(-4.9) 0 5.[(3x 4 y 7 z 12 ) 5 (–5x 9 y 3 z 4 ) 2 ] 0.
6.3 Adding, Subtracting, & Multiplying Polynomials p. 338.
Multiplication: Special Cases Chapter 4.5. Sum x Difference = Difference of Two Squares (a + b)(a – b) = (a – b)(a + b) =a 2 – b 2.
8.7 Multiplying Polynomials p.. The FOIL method is ONLY used when you multiply 2 binomials. F irst terms O utside terms I nside terms L ast terms.
Warm Up Sept Rewrite using rational exponents: 2. Simplify: 3. Simplify: 4. Simplify: 5. Simplify:
Do Now: 1. 2x 3 x 3 = ________ 2. 2x 3 3x 2 = ________ 3. 2x 3 (-2x) = ________ 4. 2x 3 5 = ________.
Objective: The student will be able to: multiply two polynomials using the FOIL method, Box method, and the distributive property.
Multiplying Polynomials. 1. Use FOIL method if you have 2 Binomials. ◦ F (first) O (outer) I (inner) L (last) 2. Use Distribution otherwise. Remember.
