Let $A = \left[\begin{array}{cc} 1 &0.25\cr -45 &-6 \end{array}\right].$ Find an invertible matrix $S$ and a diagonal matrix $D$ such that $S^{-1}AS=D$ .

$S=$ $\left[\Rule{0pt}{2.4em}{0pt}\right.$ $\left]\Rule{0pt}{2.4em}{0pt}\right.$

$D=$ $\left[\Rule{0pt}{2.4em}{0pt}\right.$ $\left]\Rule{0pt}{2.4em}{0pt}\right.$
