(2x - 4)^2 = 1;

4x^2 - 16x + 16 = 1;

4x^2 - 16x + 16 - 1 = 0;

4x^2 - 16x + 15 = 0;

(2x - 3)(2x - 5) = 0;

2x - 3 = 0; 2x = 3; x = 3/2;

2x - 5 = 0; 2x = 5; x = 5/2;

Solutions: x = 3/2 or x = 5/2

4x^2 - 16x + 16 = 1;

4x^2 - 16x + 16 - 1 = 0;

4x^2 - 16x + 15 = 0;

(2x - 3)(2x - 5) = 0;

2x - 3 = 0; 2x = 3; x = 3/2;

2x - 5 = 0; 2x = 5; x = 5/2;

Solutions: x = 3/2 or x = 5/2
