Question

Tìm x 5x^2-6x=0

Answer 1

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 \(x=\dfrac{6}{5}\)

 

Answer 2

\(5x^2-6x=0\)

\(\Leftrightarrow x\left(5x-6\right)=0\)

\(\Rightarrow\left[{}\begin{matrix}x=0\\x=\dfrac{6}{5}\end{matrix}\right.\)

  Vậy ...
