Product
The answer to a multiplication problem
Solve: (2x+3) (x+1)
2x^2 + 5x + 3
What is the Distributive Property?
The Distributive Property says that you multiply the number outside the parentheses by each number inside the parentheses.
Use FOIL to simplify:
(x + 3) (x + 5)
x^2 + 8x + 15
What is the correct order of operations according to PEMDAS?
Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
Multiplier
The number of equal groups
Solve: (3x - 4) (2x - 5)
6X^2 + (-23x) + 20
Solve using the Distributive Property: 2 × (6 + 3)
2×(6+3)=(2×6)+(2×3)=12+6=18
Simplify using the Distributive Property:
4 (2x + 7)
8x + 28
True or False:
In PEMDAS, you always do multiplication before division.**
False!
Multiplication and division are done left to right, whichever comes first.
PEMDAS Definition
Please Excuse My Dear Aunt Sally, (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction).
Solve: (2x - 3) (x^2 +2x - 3)
2x^3 + 1x^2 - 12x + 9
How can the Distributive Property help with mental math?
It breaks a hard problem into smaller, easier ones.
Solve using PEDMAS
3 + 2^2 × 4
19
Solve:
6+(4×2)
14
Distributive Property Definition?
The most powerful property in arithmetic
Solve: (3x^2 + 2x - 5) (2x^2 + 4x + 3)
6x^4 + 16x^3 + 7x^2 - 14x - 15
True or False? Is this the correct way to use Distributive property? 5 × (2 + 4) = (5 × 2) + (5 × 4)
True! This is exactly how the Distributive Property works!
5×(6)=10+20=30
Simplify using FOIL:
(x − 2) (x + 6)
-12
True or False: In PEMDAS, you always do addition before subtraction.
False.
Addition and subtraction are done left to right, depending on which comes first.
FOIL Method
First, Outer, Inner, Last; A method used for multiplying expressions
Solve: (2x - 3) (2x - 3) (2x - 3)
8x^3 - 36x^2 +54x - 27
Use the Distributive Property to simplify:
4(x+7)4(x + 7)4(x+7)
4(x+7)=4x+28
Simplify using Distributive Property:
−3 (2x − 5) -3 (2x - 5) −3 (2x − 5)
−6x + 15
