  Find matrix B if given AB=BA= (((0  0)),((0  0)) )    where A=  (((5   3)),((5   3)) ) and B ≠  (((0   0)),((0   0)) )
$$\:\:\mathrm{Find}\:\mathrm{matrix}\:\mathrm{B}\:\mathrm{if}\:\mathrm{given}\:\mathrm{AB}=\mathrm{BA}=\begin{pmatrix}{\mathrm{0}\:\:\mathrm{0}}\\{\mathrm{0}\:\:\mathrm{0}}\end{pmatrix} \\ $$$$\:\:\mathrm{where}\:\mathrm{A}=\:\begin{pmatrix}{\mathrm{5}\:\:\:\mathrm{3}}\\{\mathrm{5}\:\:\:\mathrm{3}}\end{pmatrix}\:\mathrm{and}\:\mathrm{B}\:\neq\:\begin{pmatrix}{\mathrm{0}\:\:\:\mathrm{0}}\\{\mathrm{0}\:\:\:\mathrm{0}}\end{pmatrix} \\ $$$$ \\ $$

B= (((     3),(     3)),((−5),(−5)) )
$${B}=\begin{pmatrix}{\:\:\:\:\:\mathrm{3}}&{\:\:\:\:\:\mathrm{3}}\\{−\mathrm{5}}&{−\mathrm{5}}\end{pmatrix} \\ $$
