Question

Tìm x x(2x-3)-4x+6=0 Giải giúp mình ạ mình cảm ơn

Answer 1

\(\Leftrightarrow x\left(2x-3\right)-2\left(2x-3\right)=0\\ \Leftrightarrow\left(x-2\right)\left(2x-3\right)=0\Leftrightarrow\left[{}\begin{matrix}x=2\\x=\dfrac{3}{2}\end{matrix}\right.\)

Answer 2

\(x\left(2x-3\right)-2\left(2x-3\right)=0\Rightarrow\left(2x-3\right)\left(x-2\right)=0\)

\(\Rightarrow\left[{}\begin{matrix}x=\dfrac{3}{2}\\x=2\end{matrix}\right.\)
