# Math Help - Using the matrix eigenvalue properties

1. ## Using the matrix eigenvalue properties

Hi

The following question i am having trouble solving:

the problem is question 6 not 1 ( question 1 only used to compare with)

P.S

2. ## Re: Using the matrix eigenvalue properties

What "eigenvalue properties" do you have to work with?

(i) is just A with 10 added to each number on the main diagonal.

(ii) is just B transposed and with 5 added to each number on the main diagonal.

(It's easy to find the eigenvalues directly but apparently that's not the point of this problem.)

ok the following are the properties i think they are refering to:
