3 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

Solve using the quadratic formula

x² + 4x - 40 = -8

• -10 & -4

• -4 & 10

• -8 & 4

• 8 & -4

Solve using the quadratic formula

2x² + 2x - 12?

• -2, 3

• 2, 3

• 2, -3

• -2, -3

In the equation
y = x² +5x +7, match each leading coefficient with its correct letter 

• a=0, b=5, c=7
• a=1, b=5, c=7
• a=7, b=5, c=1

Solve Using the Quadratic Formula
 x² + 4x - 40 = -8

• -10 & -4
• -4 & 10
• -8 & 4
• 8 & -4

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

• -2, 3
• 2, 3
• 2, -3
• -2, -3

If the discriminant is zero you will have

• no real solutions
• two real solutions
• 1 real solution
• 1 imaginary solution

If the discriminant is a positive number you will have.....

• two real solutions

• zero real solutions

• one real solution

• two imaginary solutions
