Consider the below given Matrix
\(M = \;\left[ {\begin{array}{*{20}{c}} { - 3}&4\\ { - 1}&2 \end{array}} \right];\;and\;I = \;\left[ {\begin{array}{*{20}{c}} 1&0\\ 0&1 \end{array}} \right]\)
Which of the following is/are correct about M2 and M3 ?
1
M2 = 2I + M
2
M2 = 2I - M
3
M3 = -3M - 2I
4
M3 = 3M - 2I
