How to work out eigenvalues of a 2x2 matrix

WebTo find eigenvalues, we use the formula: A→v = λ→v A v → = λ v → where A = (a b d c) A = ( a b d c) and →v = (x y) v → = ( x y) (a b d c)(x y) = λ(x y) ( a b d c) ( x y) = λ ( x y), … WebAnd that would be a times x. It would be the same, it'd be 3 times this length, but in the opposite direction. Because it corresponds to lambda is equal to minus 3. So anyway, we've, I think, made a great achievement. We've not only figured out the eigenvalues for a 3 by 3 matrix, we now have figured out all of the eigenvectors.
