so eigenvalues are 3,4,-1
Can you take it from here? You just gotta solve:
and these will give the the associated eigenvector to the eigenvalues.
| 1 2 0 |
A = | 3 2 0 |
| 0 0 3 |
Find the eigen values and corresponding eigenspace. I know generally how to find eigenvalues but in a 3x3 matrix I get a cubic function that I cannot find the roots for. Thanks so much for the help!
