    x = 3 x = - 1/2

    Step-by-step explanation:

    (4x-5) ^2=49

    Take the square root of each side

    sqrt ((4x-5) ^2) = ±sqrt (49)

    4x-5 = ±7

    Separate into two equations

    4x-5 = 7 4x-5 = - 7

    Add 5 to each side

    4x-5+5 = 7+5 4x-5+5 = - 7+5

    4x = 12 4x=-2

    Divide each side by 4

    4x/4 = 12/4 4x/4 = - 2/4
