Question

tìm x biết

5x^2-10x=0

Answer 1

\(5x^2-10x=0\)

\(\leftrightarrow5x\left(x-2\right)=0\)

\(\rightarrow\orbr{\begin{cases}x=0\\x=2\end{cases}}\)

Answer 2

Ta có 5x²-10x=0 

=> 5x(x-5)=0 

=> \(\orbr{\begin{cases}5x=0\\x-5=0\end{cases}\Rightarrow\orbr{\begin{cases}x=0\\x=5\end{cases}}}\)

Vậy x=0,5

Answer 3

\(5x^2-10x=0\)

\(\Rightarrow5x\left(x-2\right)=10\)

\(\Rightarrow\orbr{\begin{cases}5x=0\\x-2=0\end{cases}\Rightarrow\orbr{\begin{cases}x=0\\x=2\end{cases}}}\)

Vậy \(x=0;2\)
