Solving Quadratic Equations by Quadratic Formula

Determine the values of

a, b, and c:

4x² – 8x – 3 = 0

• a = 4, b = -8, c = 3

• a = 4, b = -8, c = -3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

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

• True

• False

Solve using the Quadratic Formula:
x² + 4x + 3 = 0

• x = 1 and x = 3
• x = 6 and x = -2
• x = -1 and x = -3

• No real solutions

Solve using the Quadratic Formula:

2x² − x − 3 = 0

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

• No solution
