\(5x\left(x-2\right)-x+2=0\)
\(\Rightarrow5x\left(x-2\right)-\left(x-2\right)=0\)
\(\Rightarrow\left(5x-1\right)\left(x-2\right)=0\)
\(\Rightarrow\left[{}\begin{matrix}5x-1=0\\x-2=0\end{matrix}\right.\Rightarrow\left[{}\begin{matrix}x=\dfrac{1}{5}\\x=2\end{matrix}\right.\)
Vậy x=1/5 hoặc x=2
a: Ta có: \(5x\left(x-2\right)-x+2=0\)
\(\Leftrightarrow\left(x-2\right)\left(5x-1\right)=0\)
\(\Leftrightarrow\left[{}\begin{matrix}x=2\\x=\dfrac{1}{5}\end{matrix}\right.\)
