Answer 9

it is a word document... ok, I have matrix \[M \in \mathbb{R} ^{2,2}\]. I have to prove that set L(M) of matrices X ( XM=0), and set R(M) of matrices X,( MX=0,) are subspaces of vector space \[\mathbb{R} ^{2,2}\] and to determine base and dimension of subspace \[L(\left[\begin{matrix}2 & 1 \\ 6 & 3\end{matrix}\right])+R(\left[\begin{matrix}2 & 1 \\ 6 & 3\end{matrix}\right])\]
