Question

What  seems to be the problem in your solution?

anonymous · Answer

(3x-1)^2 = 1/4

    then

    (3x-1) = Sqrt(1/4) = 1/2 or -1/2

    so

    3x-1 = 1/2 or -1/2.

    Add one to both sides and get:

    3x = 3/2 or 1/2

    Divide by three on both sides to get:

    x = 1/2 or 1/6


Hope this helps.
