Quadratic Formula

Determine the values of

a, b, and c for

the quadratic equation:

4x² – 8x = 3

• a= 4, b= - 8, c= 3

• a = 4, b = - 8, c = - 3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

Use the quadratic formula to solve 2x² + 2x - 12?

• -2, 3
• 2, 3
• 2, -3
• -2, -3

If the graph of a quadratic does not intercept the x-axis at any point, then it has:

• 1 Real Solution
• 2 Real Solutions
• Half a Solution
• No Real Solution
