For a square matrix A, the statement "A has an eigenvalue λ" is equivalent to the statement "(A−λI)v=0 has a non-zero solution v". Say your friend claims that the matrix A= ⎛⎝⎜91−12101−2−18⎞⎠⎟ has eigenvalue λ=8 and wants our help finding the eigenvector. We proceed by attempting to solve the system of linear equations (A−8I)v=0. That is, we try to solve the system represented by the augmented matrix ⎛⎝⎜11−1221−2−10∣∣∣∣000⎞⎠⎟. This matrix can be row-reduced to ⎛⎝⎜100230−2−21∣∣∣∣000⎞⎠⎟. Recalling our experience in Math1131, we can see this has a unique solution, namely v=
