\(4x^2-4x+3=0\)

\(\Rightarrow4x^2-4x+1+2=0\)

\(\Rightarrow\left(2x-1\right)^2+2=0\)

Vì \(\left(2x-1\right)^2\ge0\forall x\)\(\Rightarrow\left(2x-1\right)^2+2\ge2\)

\(\Rightarrow\left(2x-1\right)^2=0\)( vô lý )

\(\Rightarrow x\in\varnothing\)

\(\text{Vì }\left(2x-1\right)^2\ge0\forall x\)

\(\text{Mà}\left(2x-1\right)^2=-2\)
