Question

Tìm x

X²-2x=0

Answer 1

\(x^2-2x=0\)

xx-2x=0

x.(x-2)=0

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

Answer 2

x²-2x=0

<=> x(x-2)=0

<=> x-2=0

=> x=2

Answer 3

\(x^2-2x=0\)

\(xx-2x=0\)

\(x\left(x-2\right)=0\)

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

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

Vậy \(x=0\) hoặc \(2\)
