Step 1
Solution:
In order to show that is eigenvalue for the matrix
We need demonstrate that there is at least one vector.
such that
Consider drawing some conclusions from this situation.
If we equalize thise two equations we get:
and from here we get the following system:
1)
2)
this indicates that
3)
and 4)
but equations (3) and (4) are equivalent so we only take 4th into consideration and conclude that
This means that all eigenvectors have this form
where is random scalar different from zero. For example if we take we get the eigenvector

Step 1
Let A be an
Step 2
We must show that there is nonzero vector x such that
In other words, that equation
We have to compute the Null space of matrix
Step 3
Arbitrary vector from Null space is:
Choose any value for
