Question

1/36(x-1/2)²=1/9 ĐANG CẦN GẤP Ạ

Answer 1

`1/36 (x-1/2)^2=1/9`

`(x-1/2)^2=4 = 2^2=(-2)^2`

\(\left[{}\begin{matrix}x-\dfrac{1}{2}=2\\x-\dfrac{1}{2}=-2\end{matrix}\right.\)

\(\left[{}\begin{matrix}x=\dfrac{5}{2}\\x=-\dfrac{3}{2}\end{matrix}\right.\)

Answer 2

\(\dfrac{1}{36}.\left(x-\dfrac{1}{2}\right)^2=\dfrac{1}{9}\) 

       \(\left(x-\dfrac{1}{2}\right)^2=\dfrac{1}{9}:\dfrac{1}{36}\) 

       \(\left(x-\dfrac{1}{2}\right)^2=4\) 

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

        \(x-\dfrac{1}{2}=2\) hoặc \(x-\dfrac{1}{2}=-2\) 

               \(x=\dfrac{5}{2}\) hoặc \(x=\dfrac{-3}{2}\)
