\[
A=\left (\array{
1& 0 & 0\cr
-1 & 1 & 1 \cr
2& 1 & 0} \right ),~
B=\left (\array{
-1& 1 & 0\cr
0 & 1 & 1 \cr
1 &1& -1 } \right ).
\]
Pro kterou matici \(X\) platí \(A \cdot B - X= B^2\)?
\(
\left (\array{
-2& 1 & -1\cr
1 & -1& 0\cr
0 & 2& -1 } \right )
\)
\(
\left (\array{
-2& 1 & -1\cr
1 & 1& 0\cr
0 & 2& -1 } \right )
\)
\(
\left (\array{
-2& 1 & 1\cr
1 & -1& 0\cr
0 & 2& -1 } \right )
\)
\(
\left (\array{
2& 1 & -1\cr
1 & -1& 0\cr
0 & 2& -1 } \right )
\)
