The following is a diagonalization of the matrix $B$. $$ B=\left[\begin{array}{ccc} 4 & 0&-21 2. & 5 & 4 1 0 & 0 & 5 \end{array} ight)=\left[\begin{array}{ccc} -2 & 0& -1 W 0 & 1 & 2 1 & O & O \end{array} ight]\left[\begin{array}{ccc} 5 & 0&O 0 & 5 & 0 0 & 0& 4 \end{array} ight]\left[\begin{array}{ccc} -2 & 0& -1 W 0 & 1 & 2 1 & 0& 0 \end{array} ight]^{-1} $$ Using the diagonalization, find the eigenvalues of $B$.
