B3: Consider the matrix:
A =
-2 -3 -3
2 -1 -1
a) Find the eigenvalues of A. For each eigenvalue A, find the dimension of
the eigenspace ker(A – AI) and give a basis (i.e. find eigenvectors).
You are given that (A – 2)(A² +6A + 8) = 13 + 42 – 41 – 16.
b) Decide if A is diagonalisable. If it is, then write A as:
A = PDP-,
where D is a diagonal matrix.
c) Compute A".
