Question

\(x^2-x=0\)

\(tìmx\)

Answer 1

x²-x=0

x(x-1)=0

=>x=0 hoặc x-1=0

                   x=0+1=1

vậy x\(\in\){0;1}

Answer 2

\(x^2-x=0\)

\(x\left(x-1\right)=0\)

\(\Rightarrow\orbr{\begin{cases}x=0\\x-1=0\end{cases}\Rightarrow\orbr{\begin{cases}x=0\\x=1\end{cases}}}\)

Vậy \(x\in\left\{0;1\right\}\)
