Quadratic Formula Practice (Math 3)

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

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3
*remember right side should =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

Use the quadratic formula to solve 2x² + 2x - 12=0

• -2, 3

• 2, 3

• 2, -3

• -2, -3

What should you do first in solving this equation?

x² + 6x - 13 = 3

• Factor

• Write down: a = 1, b = 6, c = -13

• Subtract 3 from both sides.

• Add 3 to both sides.

Write this equation x² -6 = x in standard form.

• x² +6x=0

• x² -6x=0

• x² -x -6 =0

• x² +x -6

Which equation is the standard form of a quadratic function?

• f(x) = mx + b

• f(x) = a(x - m)(x - n)

• f(x) = ax² + bx + c

• f(x) = a(x - h)² + k

2x²-x -3=0

• x=-3/2  x=1
• x= 3/2 x= -1
• x= -3/2 x= -1
• x= 3/2 x= 1
