For consistency in answers reduce A M without any switching of rcnvs. One of these spaoes has dimension 2. For that set one free variable to (J for one basis vector and the other free variable to {J for the second. For all 3 eigenvectors you may scale so they are integral. Determine a diagonalization PEP1. You can use a computer to nd P\
