The range of y = -3x^2 + 6x - 2 is y < = 1 .
y = -3x^2 + 6x - 2
y = -3(x - 1)^2 + 3 - 2
y = -3(x - 1)^2 + 1
y < = 1 .

(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
