Activity 5: Teacher Jem asked her students to simplify the given expressions before
Shown were the solutions of Fred and Joana. Who got the correct answer in teh
question? Explain why the other one had the wrong answer.
1. (6r 32
(6r + 3)2
(6r+ 3)
Fred
6r • hr = 36r2
2. 6r. 3 = 18r
3. 3 = 9
6r6r=122
2.6. 3 = 18
3. 3 = 9
36r2 + 18r+ 9
12+ 188 + 9
JOANA
Your Explanation:
2. (2r - 5) (2r +5)
(2r - 5) (2r+5)
pr-5) pr+5)
2r . 2r = 4r
2r . 2r = 4r
2r • 5 10r
2r 5 = 10
-5. 2r = 10
5.5 = 25
-5 . 2r-10r
-5.5 = -25
JOANA
= 4.25
= 4n+20r - 25
