Answer:

1. x² - 6x + 2 = 0

  • a = 1
  • b = -6
  • c = 2

2. (x + 1)² = 2(x - 3)

(x + 1) × (x + 1) = 2x - 6

x² + x + x + 1 = 2x - 6

x² + 2x + 1 - 2x + 6 = 0

x² + 5 = 0

  • a = 1
  • b = 0
  • c = 5

3. (x - 1) × (x + 2) = x × (x + 5)

x² + 2x - x - 2 = x² + 5x

x² + x - 2 - x² - 5x = 0

-4x - 2 = 0

  • a = 0
  • b = -4
  • c = -2

4. (x + 2) × (x - 3) = 5

x² - 3x + 2x - 6 = 5

x² - x - 6 - 5 = 0

x² - x - 11 = 0

  • a = 1
  • b = -1
  • c = -11

5. x² + 2x + 1 = 5x + 6

x² + 2x + 1 - 5x - 6 = 0

x² - 3x - 5 = 0

  • a = 1
  • b = -3
  • c = -5
