PLEASE ANSWER II) CORRECLTY

Find the characteristic polynomial, the eigenvalues and a basis of eigenvectors associated to each eigenvalue for the matrix
3 0 0
A =
6-30
6-63
a) The characteristic polynomial is
p(r) = det(A - rI) = (-(3-r)^2)(3+r)
b) List all the eigenvalues of A separated by semicolons.
3;-3
c) For each of the eigenvalues that you have found in (b) (working from smallest to largest) give a basis of eigenvectors. If there
is more than one vector in the basis for an eigenvalue, write them side by side in a matrix. If there are fewer than three
eigenvalues, enter the zero vector in any answer fields that are not needed.
i) Give a basis of eigenvectors for the smallest eigenvalue.
