(1 point) Let A be a 3 x 3 diagonalizable matrix whose eigenvalues are 1 1 = 1, 12 = 4, and 13 = 2. If V1 = [1 0 0], V2 = [1 1 0], v3 = [0 1 1] are eigenvectors of A corresponding to 1 1 , 12, and 13, respectively, then factor A into a product XDX- with D diagonal, and use this factorization to find AS . A =
