Let $T: R^{2} ightarrow R^{2}$ be the linear operator defined by $$ T\left(\left[\begin{array}{1} x_{1} \ X_{2} \end{array} ight] ight)=\left[\begin{array}{1} 8 x_{1}-x_{2} \ 8 x_{1}+x_{2} \end{array} ight] and let $B=\left\{\boldsymbol{u}_{1}, \boldsymbol{u}_{2} ight\}$ be the basis for which $\boldsymbol{u}_{1}=\left[\begin{array}{1}1 11 8\end{array} ight), \boldsymbol{u} _{2}=\left[\begin{array}{c}-1 \ O\end{array} ight]$. Find $[T]_{B}$. $[1]_{B}=\left(\begin{array}{11}? & ? ? & ?\end{array} ight) $ CS. JG. 114 $$
