Answer:
If A=(
3
−3
−3
3
) then A
2
can be computed as shown below:
A
2
=(
3
−3
−3
3
)(
3
−3
−3
3
)=(
3×3+−3×−3
−3×3+3×−3
3×−3+(−3)×3
−3×−3+3×3
)
implies A
2
=(
18
−18
−18
18
)
Since A
2
=λA, therefore,
(
18
−18
−18
18
)=λ(
3
−3
−3
3
)
(
18
−18
−18
18
)=(
3λ
−3λ
−3λ
3λ
)
Now equating the matrices we get 3λ=18⟹λ=6.
