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