PERFORMANCE TASK
1. 1
2. (a - 1 )(a - 1) 0r a² - 2a + 1
(a + 1)(a + 1) a² + 2a + 1
Step-by-step explanation:
PERFORMANCE TASK SOLUTION
1. x + 3 . x² - 6x + 9 , FACTOR
x - 3 x² - 9
= x + 3 . (x - 3)(x - 3) , cancel out common factors
x - 3 (x - 3)(x + 3)
= 1
2. a - 1 . __a² - 1 _ , FACTOR
a + 1 a² + 2a + 1
= a - 1 . __(a - 1)(a + 1)_ , cancel out common factors
a + 1 (a + 1)(a + 1)
= (a - 1 )(a - 1)
(a + 1)(a + 1)
0r
a² - 2a + 1
a² + 2a + 1
