1. The problem statement, all variables and given/known data M: V -> V linear operator st M^2 + 1_v = 0 find the POSSIBILITIES for min. pol. of M^3+2M^2+M+3I_v 2. Relevant equations 3. The attempt at a solution using M^2 = -1_v, i rewrote the operator(?) as M^3 + M + I_v i dunno what to do. i guessed min poly to be like x^3-x-1 but what would be other possibilities. i seriously doubt the one i guessed is even correct. i know that, if min poly is u(x) then u(M) = 0.
