( 2 x - 1 ) ^ 2 = 25
Take the square root of both sidea
2 x - 1 = + OR - 5
Add 1 to both sides
2 x - 1 + 1 = + OR - 5 + 1
2 x = + OR - 5 + 1
Divide both sides by 2
x = ( + OR - 5 + 1 ) / 2
x 1 = ( 5 + 1 ) / 2 = 6 / 2 = 3
x 2 = ( - 5 + 1 ) / 2 = - 4 / 2 = - 2
Solve the quadratic equation by the square root property
(2x - 1)2 = 25
