5x2-6x=0
\(\Leftrightarrow x\left(5x-6\right)=0\)
\(\Leftrightarrow\left[{}\begin{matrix}x=0\\5x-6=0\end{matrix}\right.\)
\(\Leftrightarrow\left[{}\begin{matrix}x=0\\5x=6\end{matrix}\right.\)
\(\Leftrightarrow\left[{}\begin{matrix}x=0\\x=\dfrac{6}{5}\end{matrix}\right.\)
Vậy \(x=0\) hoặc \(x=\dfrac{6}{5}\)
\(5x^2-6x=0\)
\(\Leftrightarrow x\left(5x-6\right)=0\)
\(\Rightarrow\left[{}\begin{matrix}x=0\\x=\dfrac{6}{5}\end{matrix}\right.\)
Vậy ...
\(5x^2-6x=0\)
\(\Leftrightarrow x\left(5x-6\right)=0\)
\(\Leftrightarrow\left[{}\begin{matrix}x=0\\x=\dfrac{6}{5}\end{matrix}\right.\)
