( 2 A-B=left[begin{array}{rrr}2 & -1 & 5 2 & -1 & 6 0 & 1 & 2end{array}right] . . ) is in ( A+2 B=left[begin{array}{ccc}1 & 2 & 0 6 & -3 & 3 -5 & 3 & 1end{array}right] ) ( therefore frac{2(i)+(11)}{5}=A=left[begin{array}{ccc}1 & 0 & 1 2 & -1 & 3 -1 & 1 & 1end{array}right] ) ( frac{2|i|-(i)}{5}=B=left[begin{array}{ccc}0 & 61 & -1 2 & -1 & 0 -2 & 1 & 0end{array}right] ) ( T_{r}(A)+operatorname{Tr}(B)=mid-1+1-1 ) ( =0 )
