(dấu ^ là mũ nhỉ)
\(\left(x-\dfrac{1}{2}\right)^2=\dfrac{9}{16}\)
\(\left(x-\dfrac{1}{2}\right)^2=\left(\dfrac{3}{4}\right)^2\)
\(x-\dfrac{1}{2}=\dfrac{3}{4}\) \(hay\) \(x-\dfrac{1}{2}=-\dfrac{3}{4}\)
\(x=\dfrac{3}{4}+\dfrac{1}{2}\) \(x=-\dfrac{3}{4}+\dfrac{1}{2}\)
\(x=...\left(tutinh\right)\) \(x=...\left(tutinh\right)\)
Vậy …
