Question 5. For each of the following matrices, perform two iterations of the power method by hand starting with a vector of all ones. State the resulting approximations of the eigenvalue and eigenvector. $$ \begin{array}{1} A=\left[\begin{array}{11} 1 & 2 3 & 4 \end{array} ight] B=\left[\begin{array}{ccc} 2 & -1 & ON -1 & 2 & -1 W & -1 & 2 \end{array} ight] \end{array} $$ CS.VS. 1598
