Answer 2

1. The expression x² - 2xy + y² cannot be factored further.

2. The expression 36a²c - 49b²c can be factored as (6ac - 7bc)(6ac + 7bc).

3. The expression -49 + 4x² can be factored as (2x - 7)(2x + 7).

8a³ - 4a² - 24a can be factored as 4a(a - 2)(2a + 3).

9. The expression (x + 2)² - 9x² can be factored as (x - 1)(x + 3)(2x + 1).
