Quadratic Equation

Solve the following quadratic equation...

x² + 9x + 20 = 0

• x = -2

  x = -10

• x = -5

  x = -4

• x = -1

  x = -20

• x = 4

  x = 5

Solve by completing the square.
x² + 4x= 12

• x = 2 and -2
• x = -6 and 2
• x = 6 and -2
• x = 1 and -1

Solve by factoring: x² = 7x + 18

• -7 and -18

• 9 and 2

• 9 and -2

• 2 and 7
