Answer:

19 is right answer i thnik so

Answer 2

Answer:

f ( λ )= λ 2 − Tr ( A ) λ + det ( A ) . This is generally the fastest way to compute the characteristic polynomial of a 2 × 2 matrix.

Step-by-step explanation:

Find the characteristic equation and the eigenvalues (and corresponding eigenvectors) of the matrix. 2 -2 7 0 3 -2 0 -1 2 (a) the characteristic equation (b) the eigenvalues (Enter your answers from smallest to largest.) (91, 12, 13) = 1, 2, 4 the corresponding eigenvectors X1 = x X2 = X3 =
