(1) 2x - 1 = X is given; %3D (2) 2x (1); - 1 : x ,obtained by squaring both sides of 2 X - 1 = 0, obtained by subtracting x from both (3) sides of (2); (4) (x – 1) (x + 1) = 0, obtained by factoring the %3D 2 left-hand side of x - 1; -%3B (5) implies that a = 0 or b = 0. X = 1 or X = -1, which follows because ab = 0 %3D
