Question

Cut points of (x-2)(x+2)(3x-1)≤0:
a. 2, -2, 3
b. 2, -2, -1/3
c. 2, -2, 1/3
d. 2, -2, -3

Answer 1

Well, do you know what valeus of x will make (x-2)(x+2)(3x-1) 0?

Answer 2

(x-2)(x+2)(3x-1) = 0 is what I mean. What x values make that true?

Answer 3

Is the answer c.? I just need clarification

Answer 5

Yes. But you probably didn't need to use Alpha. If you look at
(x-2)(x+2)(3x-1)
(x-2) = 0 gives me x=2
(x+2) = 0 gives me x=-2
(3x-1) = 0 gives me x=(1/3)

Answer 6

Oh I see. Thank you for the explanation and the clarification!

Answer 7

You're quite welcome =)
