(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a matrix A:

[1 3 0

3 1 0

0 0 -2]

Find Q and D where

Q^{T}AQ=D

3. The attempt at a solution

I found the eigenvalues of -4,2,2

When I plug them back in and rref the matrix I only get the trivial solution meaning the matrices are linearly independent. How do I get the eigenvectors if that's the case?
