Hi! I'm having trouble with the following question: "Solve the following quadratic formula by completing the square: x^2 -2x +a = 0 " So far, I'm managed to find out that a)The equation has 2 distinct roots because "b^2 -4ac" = positive b) One of the roots is 1. My textbook says that the other answer is sqrt(1-a) but I can't get that answer. My calculations show that the answer should be (sqrt(1-a) + 1 ) Could you please show working? Thanks in advance!
