I believe you are trying to factor the polynomial. so x^2 -4x+3 (x-1)(x-3) =0 x= 1,3

Pre-Calc-Please check my answer
x^2 -4x + 3 = 0 factor (x-3)(x-1) = 0 x = 3 or x = 1 or complete the square as you tried x^2 -4 x = -3 note sign change of 3 x^2 - 4 x + 4 = -3 +4 = 1 (x-2)^2 = 1 x = 2 +/- 1 x = 1 or x = 3
