What are the eigenvalues of the upper triangular matrix A=[2530−17004]A = \begin{bmatrix} 2 & 5 & 3 \\ 0 & -1 & 7 \\ 0 & 0 & 4 \end{bmatrix}A=2005−10374?
λ=2,5,3\lambda = 2, 5, 3λ=2,5,3
λ=2,−1,4\lambda = 2, -1, 4λ=2,−1,4
λ=2,−1,7\lambda = 2, -1, 7λ=2,−1,7
The eigenvalues cannot be determined without computing the characteristic polynomial.
