±81±9±3No real solution - 2. Multiple Choice-2, 4-8±8No real solution
- 3. Multiple Choice-4, 2-2, 4-16-4
- 4. Multiple ChoiceFind the zeros of this quadratic.b=4/5, b=3b=4, b=-3b=1/5, b=3b=4/5, b=-3
- 5. Multiple ChoiceDetermine the values of
a, b, and c for
the quadratic equation:
4x2 – 8x = 3a = 4, b = -8, c = 3a = 4, b =-8, c =-3a = 4, b = 8, c = 3a = 4, b = 8, c = -3 - 6. Multiple ChoiceSuzie solves the equation below:
x2 + 4x - 12 = 2
(x - 2)(x + 6) = 2,
by setting x -2 = 0 and x + 6 = 0.
Her solutions are x = 2 and x = -6.
Is Suzie correct? Why or why not?Yes, she factored correctly and then used the zero product propertyYes, she factored correctly and then square rooted.No, she did factor correctly, but she can't use the zero product property as shown.No, she didn't factor correctly so the rest of her work is wrong. - 7.
