\(x^3=x^2\)
\(\Leftrightarrow x^3-x^2=0\)
\(\Leftrightarrow x^2\left(x-1\right)=0\)
\(\Leftrightarrow\orbr{\begin{cases}x^2=0\\x-1=0\end{cases}\Leftrightarrow\orbr{\begin{cases}x=0\\x=1\end{cases}}}\)
Vậy x = 0 hoặc x = 1
Nếu
x^3=x^2
Thì có 2 trường hợp
TH1: x=1
x^3=x^2=1
TH2: x=0
0^3=0^2=0
Vậy x=1,0
\(x^3=x^2\)
\(\Leftrightarrow x^3-x^2=0\)
\(\Leftrightarrow x^2\left(x-1\right)=0\)
\(\Leftrightarrow\orbr{\begin{cases}x^2=0\\x-1=0\end{cases}}\)
\(\Leftrightarrow\orbr{\begin{cases}x=0\\x=1\end{cases}}\)
Vậy \(x\in\left\{0;1\right\}\)
