Solve Quad

Solve the following quadratic equation...

x² + 13x + 36= 0

• x = -2

  x = -18

• x = -9

  x = -4

• x = -3

  x = -12

• x = -6

  x = -6

Solve using the Quadratic Formula:

x² + 6x + 9 = 0

• x = −3, 3

• x = −3

• x = 3

• No Solution

Solve using the Quadratic Formula:

15x² + 22x = −8

• x = −2/3, 4/5

• x = 2/3, −4/5

• x = 2/3, 4/5

• x = −2/3, −4/5

Solve by factoring: x² - 9x + 20 = 0

• x = -4 and x = -5

• x = 20 and x = -9

• x = 4 and x = 5

• x = -4 and x = 5

2d² = 8

• 4

• -2

• -4, 4

• -2, 2
