Let the given matrix M acts on the given vector [3,2]^t.
In other words, calculate the vector
= ..
Since the given vector is eigenvalue vector
(by the way, notice how I write this word --- and LEARN/memorize it (!) )
the resulting vector will be proportional to the given vector:
the resulting vector = .
The proportionality coefficient "k" in this equation is the eigenvalue you are seeking for.
After my explanations, boldly go forward and do the rest on your own.
