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
