2. Objective #1: Multiply a monomial and a polynomial.
6(x + y)
How would we multiply this problem?
DISTRIBUTIVE PROPERTY
6x + 6y
We will use the distributive property to multiply monomials and polynomials.

3. Examples:
1.)
2.)

4. Objective #2: Multiply two binomials.
We can use the distributive property twice to multiply two binomials.
3.) (x + 4)(x + 5)
x(x) + x(5) + 4(x) + 4(5)

5. F.O.I.L Use F.O.I.L to find the product of two binomials. First

6. Examples: 4.) (x + 3)(x – 2) binomial times binomial First: x(x) =
Outside: x(-2) = -2x
Inside: 3(x) = 3x
Last: 3(-2) = -6
Is your answer in descending order?

7. 5.) (3x + y)(-3x – 4y)
First: 3x(-3x) =
Outside: 3x(-4y) =
Inside: y(-3x) =
Last: y(-4y) =
