Slide for simplification of like terms

1. Simplifying Expressions: Discuss: Which of these expressions contain a pair of like terms? How do you know?      

2.                   Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike In pairs: Decide which expressions contain ONLY like terms

3.                 Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike   Like / Unlike

4.         Like / Unlike Like / Unlike Like / Unlike Like / Unlike

5.                   Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike

6.                 Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike   Like / Unlike

7.         Like / Unlike Like / Unlike Like / Unlike Like / Unlike

8.           Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike Your Turn: In your books copy and complete the following:

9. Mark your work           Like / Unlike Like / Unlike Like / Unlike Like / Unlike Like / Unlike

10. Collecting ‘like’ terms Algebraic expressions can be simplified by collecting like terms " Like terms " are  terms  whose variables ( and their powers such as the 2 in x 2 ) are the same . The coefficients may be different.

11. Simplify a a a a a a + a + a + a + a = 5a 5a

12. And another… 3c + 2c + c = 6c 3c 2c c 6c

13. And another… 5d 4d d 5c 4d + d + d – d = d -d

14. And another… 2e 2 e 2 3e 2 e 2 + 2e 2 = 3e 2

15. And another… 3b b 2a + 3b + 4a + b = 6a + 4b 2a 4a 2a 4a 3b b 3b b 2a 4a 6a + 4b

16. And another… -3b b -2a - 3b + 4a + b = 2a – 2b -2a 4a

17. On your whiteboards… Simplify the following expressions by collecting like terms.

18. 4 d + d + 3d 8d

19. 5 d -2d + 3d 6 d

20. 5p + 4q – 2p + q 3p + 5q

21. 5s - t +s + t 6s

22. 2p 2 +3p 2 – 4p 2 p 2

23. 3p q - 4 + 5pq 8pq - 4
