\(\left(x+\frac{1}{2}\right)^2=\frac{1}{6}\)
\(\left(x+\frac{1}{2}\right)=+-\sqrt{\frac{1}{6}}\)
Khi :
\(\left(x+\frac{1}{2}\right)=\frac{1}{6}\)
\(x=\frac{1}{6}-\frac{1}{2}\)
\(x=-\frac{1}{3}\)
Khi
\(\left(x+\frac{1}{2}\right)=-\frac{1}{6}\)
\(x=-\frac{1}{6}-\frac{1}{2}\)
\(x=-\frac{2}{3}\)

\(\left(x+\frac{1}{2}\right)^2=\frac{1}{6}\)
\(\Rightarrow x^2+\left(\frac{1}{2}\right)^2=\frac{1}{6}\)
\(\Rightarrow x^2+\frac{1}{4}=\frac{1}{6}\)
\(\Rightarrow x^2=\frac{1}{6}-\frac{1}{4}=\frac{-1}{12}\)
\(\Rightarrow x^2=\frac{-1}{12}\)

\(\left(x+\frac{1}{2}\right)^2=\frac{1}{6}\)
=>\(x^2+\frac{1}{2}^2=\frac{1}{6}\)
\(x^2+\frac{1}{4}=\frac{1}{6}\)
\(x^2=\frac{1}{6}-\frac{1}{4}=-\frac{1}{12}\)
\(x=\sqrt{-\frac{1}{12}}\)
