    your equation is x^2-2x+6=0 now take the constant to RHS x^2-2x = -6 look to LHS of this equation what should i add to make it perfect square like it become (a+b)^2 or (a-b)^2

    so if i add 1 to LHS and RHS then LHS become a perfect square x^2-2x+1 = -6+1 (x-1)^2 = -5 this LHS has became a perfect square by adding 1 to it
