Answer:

1. - 49 = 0

(x + 7)(x - 7) = 0

x + 7 = 0 or x - 7 = 0

x = 7 or x = -7

2. 9x² - 25 = 0

(3x + 5)(3x - 5) = 0

3x + 5 = 0 or 3x - 5 = 0

x = -5/3 or x = 5/3

3. 4x² + 1 = 5

4x² + 1 - 5 = 0

4x² - 2 = 0

- 1 = 0

(x + 1)(x - 1) = 0

x + 1 = 0 or x - 1 = 0

x = -1 or x = 1

4. 5(x + 7)² = 1125

(x + 7)² = 225

x + 7 = 225 or x + 7 = -255

x = 8 or x = -22

5. x² = 43

x = 43 or x = -43
