Yes, they mean the same thing. if det(λi a) = 0, then det(a λi) = 0.this is because, if you multiply a matrix, like λi a, by a scalar, like 1, so that you get a λi, the determinant of the new matrix is just the determinant of the old matrix times that scalar raised to the power of the number of dimensions of the matrix. Or we could say that the eigenspace for the eigenvalue 3 is the null space of this matrix. which is not this matrix. it's lambda times the identity minus a. so the null space of this matrix is the eigenspace. so all of the values that satisfy this make up the eigenvectors of the eigenspace of lambda is equal to 3. Besides these pointers, the method you used was pretty certainly already the fastest there is. other methods exist, e.g. we know that, given that we have a 3x3 matrix with a repeated eigenvalue, the following equation system holds: ∣∣∣tr(a) = 2λ1 λ2 det(a) =λ21λ2 ∣∣∣ | tr ( a) = 2 λ 1 λ 2 det ( a) = λ 1 2 λ 2 |.

Finding the eigenvectors and eigenvalues of a matrix a a a comes down to finding values of v \mathbf{v} v and λ \lambda λ that make this expression true. it's a little awkward to work with at first, because the left hand side represents matrix vector multiplication, while the right hand side is scalar vector multiplication.
