Quadratic Formula

Determine the values of
a, b, and c for
the quadratic equation: 
2x² – 6x = 4

• a = 2, b = -6, c = 4

• a = 2, b =-6, c =-4

• a = 2, b = -6, c = 4

• a = 2, b = -6, c = 4

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

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

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

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

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 3x = -5
*remember right side should =0

• a = 4, b = -3, c = 5

• a = 4, b =-3, c =-5

• a = 4, b = 3, c = 5

• a = 4, b = 3, c = -5

Identify the 'b' value: y = 16x² -8x -24
