Quadratic Equations by Quadratic Formula

Solve the following quadratic equation using Quadratic Formula

2x² - 3x - 5 = 0

• x = -1

  x = 5/2

• x = 5

  x = 2

• x = -1/2

  x = 5

• x = 1/2

  x = -5/2

• No solution

Solve using the Quadratic Formula:

2x² + 2x − 12 = 0

• x = −2, 3

• x = 2, 3

• x = 2, −3

• x = −2, −3

The quadratic formula can be used to solve quadratic equations that cannot be factored.

• True

• False

What is this formula?

• This is the speed of light formula.

• This is the quadratic formula.

• This is the zero product property.

• This is scary.
