Hello, a walkthrough would be appreciated, thanks so much :)

[1 1pts] Consider the following matrix: oo 0 M = 3 One of the eigenvalues of M is equal to 7. a. What are the other two eigenvalues? (Enter the lesser one first, i.e., the less positive or the more negative.) Answers: b. What are the three normalized eigenvectors associated with the three eigenvalues of M? (Enter them in order of the eigenvalues, from least to greatest, i.e., the first eigenvector is associated with the least positive or most negative eigenvalue, etc.) x1 = X = * 3 (For part (b), enter 4 digits of precision. Your answers must be within 0.5% to be marked correct.)
