Help please!! Be sure answer all clearly

Given the following, -3 5 A = -1 3 21 = -2, X2 = X3= 8 3 0 a33 A. ( ;) Find the values of a11, a22, and a23 such that x is an eigenvector of matrix A and 1, is the corresponding eigenvalues. B. } Given the other 2 eigenvectors, x, and x2, find the remaining two eigenvalues, 1, and 12, of A. C. 1 ) Based on your answers from part A and part B, state why matrix A is diagonalizable. D. :}Write down the matrix of eigenvectors X = [x1, x2, x3] and the diagonalization matrix A
