Combining Like Terms - Page Text Content

FC: Combining | Like Terms

1: By Sage Cudney 2nd Period

2: Vocabulary | Terms - separated by a sign | There are three terms on the example above.

3: Coefficient - the number next to the variable. You must have a variable to have a coefficient. | Vocabulary | ____ | ____

4: Vocabulary | Constant - a number without a variable | ___

5: Using Commutative and Distributive Properties

6: Distributive | The distributive property makes the problem much easier. When using this while combining like terms, it gets rid of parentheses. | 5 (2y + 6n) = (5 2y) + (5 6n) | + | +

7: Examples | 3 (3k - 1p) = (3 3k) - (3 1p) | + | + | 2 (4p 7n) = (2 4p) (2 7n) | + | + | + | + | 9 (6k + 3y) = (9 6k) + (9 3y) | + | +

8: Commutative | The commutative property means to exchange or swap over. Which means that when you add or multiply, you can do it in any order. | a + b = b + a

9: Examples | 3n + 6n = 6n + 3n | 4b 5b = 5b 4b | + | + | 6x + 7x = 7x + 6x

10: Now lets practice.! | Using Commutative Property: | 4a + 6y + 20a + 3 | 4x 3 2e 5 | + | + | +

11: Using Distributive Property: | 4(3n 6j) + 7 | 9(3k - x) 5 | + | 6(2p 4z) + 9 | + | +
