What are the possible of x if (4x-5)^2=49? Check all that apply

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
