1. Multiply Binomials
SWBAT multiply binomials using the distributive property; multiply binomials using the FOIL method

2. Multiplying Binomials
To multiply binomials, apply the distributive property
(2x + 6)(2x + 4)
(2x)(2x) + (2x)(4) + (6)(2x) + (6)(4)
4x2 + 8x + 12x + 24
Combine like terms to simplify
4x2 + 20x + 24

3. Multiplying Binomials
Remember the steps using the FOIL acronym F
First O
Outer I
Inner L
Last
(4a + 3)(2a – 1)
(4a + 3)(2a – 1)
(4a + 3)(2a – 1)
(4a + 3)(2a – 1)

4. Multiplying Binomials
Use the box method
(2z – 5)(z – 8)
2z2 -8z -5z + 40
2z2 -13z + 40 z -8 2z
First
2z*z
2z2
Outer
2z*(-8)
-8z -5
Inner
-5*z
-5z
Last
-5*(-8) 40

5. Examples (x + 2)(z + 1) (y + 3)(y – 4) (a – 5) (a – 7) (3x + 2)(x + 4)
(5b + 9)(b – 4)
(2n – 7)(3n + 3)
(2x – 5)(2x – 5)
(8r2 – 2r)(5r + 4)
(2x + 5y)(7y – 3x)
