A [ 1 2 1 ]^T = 6 [ 1 2 1 ]^T

A [ 1 -1 1 ]^T = 3 [ 1 -1 1 ]^T

A [ 2 -1 0]^T = 3 [ 1 -1 1]^T

Find the Eigenvalues and eigenvectors:

I have in mind to start with the Av=λv or det(A-λI)v=0....

Also, the first 2 equations seems to have the form Av=λv:

So maybe, u1= [ 1 2 1 ] with λ=6 and u2= [1 -1 1] with λ=3 .......but what about 3rd ?
