- 1. Multiple Choice
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. - 2. Multiple ChoiceDetermine the values of
a, b, and c for
the quadratic equation:
4x2 – 8x = 3
*remember right side should =0a = 4, b = -8, c = 3a = 4, b =-8, c =-3a = 4, b = 8, c = 3a = 4, b = 8, c = -3 - 3. Multiple ChoiceSolve by factoring: x2 - 9x + 20 = 0x = -4 and x = -5x = 20 and x = -9x = 4 and x = 5x = -4 and x = 5
- 4. Multiple Choice
Solve by using the quadratic formula.
7x2 - 26x - 8 = 0
x = -1 and x = -7/8
x = 4 and x = -2/7
x = -4 and x = 2/7
x = 4 and x = -7/2
- 5. Multiple Choice
Solve
2x2 + 7x - 15 = 0
x = -1.5 and x = 5
No Solution
x = -5 and x = 1.5
x = 0.7 and x = 5
- 6. Multiple Choice
Solve for x. Round to the nearest hundredth if necessary.
3x2 = 16x + 12
x = -0.67 and x = 6
x = -6 and x = 0.67
x = 3.33 and x = 18
x = -3.33 and x = 18
- 7. Multiple Choice
Solve for x. Round to the nearest hundredth if necessary.
2x2 = -x + 3
x = -1 and x = 1.5
x = 1.5 and x = -1
x = 1 and x = 1.5
x = -1.5 and x = 1
- 8. Multiple Choice
Solve Using the Quadratic Formula
x2 + 4x - 40 = -8
x = -10 and x = -4
x = -4 and x = 10
x = -8 and x = 4
x = 8 and x = -4
- 9. Multiple Choice
Solve using the quadratic formula.
2x2 - 9x - 35 = 0
x = 7/2 and x = -6
x = -5/2 and x =5
x = -3/7 and x =6
x = -5/2 and x = 7
- 10. Multiple Choice
Use the quadratic formula to solve: n2 = 9n - 20
n = 4 and n = -5
n = -4 and n = 5
n = -4 and n = -5
n = 4 and n = 5
- 11. Multiple Choice
Use the Zero Product Property to solve for the values of x.
x = 2 and x = 3
x = -2 and x = -3
x = 2 and x = -3
x = -2 and x = 3
