Let A3 × 3 is a real symmetric matrix and λ1 and λ2 are the eigen values of the matrix. The corresponding eigen vector is \(\left[ {\begin{array}{*{20}{c}} 2\\ 2\\ \lambda \end{array}} \right]\) and \(\left[ {\begin{array}{*{20}{c}} 1\\ 0\\ 1 \end{array}} \right]\) respectively.
Thus for both λ1 and λ2 ≠ 0, the correct value of λ is _____.
1
2
2
-2
3
