Question

Tìm x

\(x.\left(x-\dfrac{2}{3}\right)=0\)

Answer 1

x.(x-\(\dfrac{2}{3}\))=0

=>x=0 hoặc x-\(\dfrac{2}{3}\)=0

=>x=0 hoặc x=\(\dfrac{2}{3}\)

Vậy x\(\in\left\{0,\dfrac{2}{3}\right\}\)

Answer 2

\(x.\left(x-\dfrac{2}{3}\right)=0\)

\(\Rightarrow\left[{}\begin{matrix}x=0\\x-\dfrac{2}{3}=0\Rightarrow x=0+\dfrac{2}{3}=\dfrac{2}{3}\end{matrix}\right.\)

Vậy \(x=0\) hoặc \(x=\dfrac{2}{3}\)

Answer 3

x . ( x - \(\dfrac{2}{3}\) ) = 0

\(\Rightarrow\) x - \(\dfrac{2}{3}\) = 0

\(\Rightarrow\) x = \(\dfrac{2}{3}\) .
