Đặt \(2x^2-3x+1=t\)
\(\Rightarrow t^2-3\left(t-6\right)-16=0\)
\(\Leftrightarrow t^2-3t+2=0\Rightarrow\left[{}\begin{matrix}t=1\\t=2\end{matrix}\right.\)
\(\Rightarrow\left[{}\begin{matrix}2x^2-3x+1=1\\2x^2-3x+1=2\end{matrix}\right.\) \(\Rightarrow\left[{}\begin{matrix}2x^2-3x=0\\2x^2-3x-1=0\end{matrix}\right.\)
