For $\alpha, \beta \in \mathbb{R}$, suppose the system of linear equations
$$ \begin{aligned} & x-y+z=5 \\ & 2 x+2 y+\alpha z=8 \\ & 3 x-y+4 z=\beta \end{aligned} $$
has infinitely many solutions. Then $\alpha$ and $\beta$ are the roots of :
$$ \begin{aligned} & x-y+z=5 \\ & 2 x+2 y+\alpha z=8 \\ & 3 x-y+4 z=\beta \end{aligned} $$
has infinitely many solutions. Then $\alpha$ and $\beta$ are the roots of :
