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

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.

Solve for z.
z² = 2z + 24

• z = -4 or z = 6
• z = -8 or z = 3
• z = -2 or z = 12
• z = -3 or z = 8

Solve by factoring:

x² + 6x + 20 = -3x

• x = -2, x = -10

• x = -3, x = -4

• x = -4, x = -5

• x = -4, x = -6
