Verified answer
For Column 1:
1.(a² + 6a + 5) / (a + 1)
(a + 1)(a + 5) / (a + 1)
a + 5
2. (3a + 1) / (3a + 1) = 1
For Column 2:
1. (3a² - 6a) / (a - 2)
3a(a - 2) / (a - 2)
3a
2. (a³ + 2a² + a) / (3a² + 6a + 3)
a(a² + 2a + 1) / 3(a² + 2a + 1)
a / 3
For Column 3:
1. (a - 1) / (1 - a)
(a - 1 ) / -(a - 1)
-1
2. (a³ + 125) / (a² - 25)
(a + 5)(a² - 5a + 25) / (a - 5)(a + 5)
(a² - 5a + 25) / (a - 5)
