x = 1. Add 3 to both sides, then factor the left.

Take zero as the smallest magnitude. So, x²-4x+3=0 . By solving, we get x²-3x-x+3=0, work out to x(x-3)-1(x-3)=0 (x-3)(x-1)=0 So, x may be 3 or 1, where 1<3.

x^2 - 4x = - 3 x^2 - 4x + 3 = 0 (x - 3)(x - 1) = 0 Solutions: x = 1 x = 3

(x-3)(x-1) = 0 x = 1

Rearrange: X^2 - 4X + 3 Factor: (X - 3)(X - 1) Solve: X = 1 is smaller.
