If $\text{f}(\text{x})=\begin{cases}\text{x}^{2}-1 & 0<\text{x}<2\\2\text{x}+3, & 2\geq\text{3}<3\end{cases}$ then the quadeatic equation whose roots are $\lim\limits_{\text{x} \rightarrow 2^{-}}\text{f}(\text{x})$ and $\lim\limits_{\text{x} \rightarrow 2^{+}}\text{f}(\text{x})$ is:
$\text{x}^{2}-6\text{x}+9=0$
$\text{x}^{2}-7\text{x}+8=0$
$\text{x}^{2}+14\text{x}+49=0$
$\text{x}^{2}-10\text{x}+21=0$
