  • Question 4
    300 seconds
    Q. Find the zeros of this quadratic.
    answer choices
    b=4/5, b=3
    b=4, b=-3
    b=1/5, b=3
    b=4/5, b=-3
  • Question 5
    300 seconds
    Q. Determine the values of
    a, b, and c for
    the quadratic equation: 
    4x2 – 8x = 3
    answer choices
    a = 4, b = -8, c = 3
    a = 4, b =-8, c =-3
    a = 4, b = 8, c = 3
    a = 4, b = 8, c = -3
  • Question 6
    300 seconds
    Q. Suzie 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?
    answer choices
    Yes, she factored correctly and then used the zero product property
    Yes, 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.
