Answer 2

Let's simplify each of the given expressions:

1. x² - 16x + 70 = (x + 8)² + 6

2. x² + 4x - 4 = (x + 2)² - 4

3. 9a² - 6a + 6 = 3(3a² - 2a + 2)

4. 4b² - 12b = 4b(b - 3)

5. 9c² - 30c + 35 = (3c - 5)²

6. 16m² + 56m - 19 = 16m² + 38m + 18 = 2(8m² + 19m + 9)

So, these are the simplified forms of the given expressions.
