1. The problem statement, all variables and given/known data

find eigenvalues and eigenvectors of matrix A =

102

012

223

2. Relevant equations

A -λI etc blah

3. The attempt at a solution

I'm getting λ = 1, -1, 5.

For λ = 1, v = (-1,1,0)t (t being a real integer constant), and double checking says it's right.

For λ = -1, i'm getting v = (1,1,1)t but if i double check by multiplying it with the matrix A i'm not getting something in the form of v (i'm getting like.. 3,3,7, which doesnt make sense to me).

For λ = 5, i got v = (1,1,2)t but again double checking doesnt give a vector in this form! (multiplying this v by A gives me 3,3,14) :angry:

what am i doing wrong??
