tìm x

Answer 1

\(a,\Rightarrow x\left(x-2\right)=0\Rightarrow\left[{}\begin{matrix}x=2\\x=0\end{matrix}\right.\\ b,\Rightarrow\left(x-1\right)\left(3x-1\right)=0\Rightarrow\left[{}\begin{matrix}x=1\\x=\dfrac{1}{3}\end{matrix}\right.\)

Answer 2

a. \(\left[{}\begin{matrix}x=0\\x-2=0\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x=0\\x=2\end{matrix}\right.\)

b. \(\left[{}\begin{matrix}3x-1=0\\x-1=0\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x=\dfrac{1}{3}\\x=1\end{matrix}\right.\)
