• You are about to see a pair of numbers that may or may not be like terms. • Based on the results, determine the rules for like terms.
Like Terms
•Yes = • No =
Like Terms
Like Terms
Like Terms
Like Terms
Like Terms
Now you determine
What are the Rules for Like Terms
•1.) They must have the same Variable. •2.) They must have the same Exponent.
Combine Like Terms The Rules for algebra apply to all LikeTerms
•Ex.. 3x + 4x • 7x
•Example 1 •3x + 6 + 5x •3x + 5x + 6 •8x + 6
Combine Like Terms
•3x + 2y + 2x + 2 •3x + 2x + 2y + 2 •5x + 2y + 2
•Example 2
Combine Like Terms
•Example 3
2 •3x 2 •5x
Combine Like Terms
2 2x
+ 2x + +2 2 + 2x2 + 2x + 2 •3x + 2x + 2
• Find the Area of the Rectangle
Distributive Property
•2 • 3 + 2 • x = 6 + 2x
• Find the Area of the Rectangle
Distributive Property
•2 (3 + x) =(3+x)+(3+x) •6 + 2x
So…….
•2 • 3 + 2 • x = 6 + 2x •2 (3 + x) = 6 + 2x Therefore ….
•2 (3 + x) =2 • 3 + 2 • x
Use the distributive Property to simplify the following
• 1.) 3(4 + x) • 1.) 12 + 3x • 2.) -2(3 + x) • 2.) -6 -2x • 3.) 5(x - 7) • 3.) 5x - 35 • 4.) 2(x - 3) + 4 • 4.) 2x -2 2- 3 • 5.) x(2 + 6x) - 3• 5.) 2x +6x
Find the Mistake •1.) 3(x + 2) = 3x + 2 • 3(x + 2) = 3x + 6 •2.) (x + 4)5 = x + 20 • (x + 4)5 = 5x + 20
Find the Mistake •3.) 4(x - 6) = 4x + 24 • 4(x - 6) = 4x - 24 •4.) 2(6 - x) = 12 - x • 2(6 - x) = 12 - 2x
Find the Mistake •5.) 3(x + 5) = 3x + 8 • 3(x + 5) = 3x + 15 •6.) -2 + x + 6 = 4x • -2 + x + 6 = x + 4
