A represents T in starndart basis
find 4 subspaces which are “T saved” (dont knpw the proper term
T saved means if v inside W subspace then Tv in W too
i have found two eigenvectors one for eigen value 2
and another eigen vector for eigen value 3.
span of each one of those eigen vectors makes Tsaved subspace.
also this A is not diagoisable.
so how do i find the other two T saved subspaces?
