Aim: How do we multiply a binomial by a binomial?
Do Now: 1. 4x (x + 5)
2. 3x ( + 3x -2)
Agenda

Homework #6
1) (b -8) (b – 10)2) (6 + y) (5 + y)3) (x – 3) ( x -3)4) (5x – 2) (x – 2)
Answers to homework #5
1. 3(x+4) = 3x + 122. 4 (3x +2) = 12 3. y(x+4) = yx + 4y4. 7z(6) = 42 z5. -5(15c – 4c) = -55
What do we remember about distributive property?
Remember how we multiply a monomial and polynomial…
(4x) (3x + 5) = (4x) (3x) + (4x) (5) = 12 + 20xLet’s try…
Double Distributive (4x + 5) (3x – 5)
1) Multiply (distribute) the first term times EACH of the terms in the second binomial.
2) Multiply the second term times EACH of the terms in the second binomial.
(4x + 5) (3x – 5)
3)Multiply the terms(4x)(3x) + (4x)(-5) + (5)(3x) + (5)(-5)
4) Add like terms
Together again!
(x + 3) (x-4)
Practice!
1. (x + 4) (x + 4)
2. (x + 5)(x+ 6)
3. (x+ 5) (x -1)
What does mean?
Perform the indicated property:
Together!
Practice!
