I'm tasked with finding the characteristic equation, eigenvalues, and bases for the eigenspaces of this matrix [1, -3, 3] [3,-5,3] [6,-6,4] After working on the problem, I believe the characteristic equation is (λ + 2)^2(λ-4), giving eigenvalues of -2 and 4 (please correct me if I'm wrong). However, I'm lost when finding the bases for the eigenspace because I'm not sure the eigenvectors I get are linearly independent.
