WebSep 28, 2024 · No, it's not diagonalizable. If the two eigenvalues of a 2 × 2 matrix were distinct, it would be; when they're the same, it might be (but in this case it's not). The eigenvalues of an n × n matrix turn out (as you'll probably learn soon) to be the roots of a degree- n polynomial. WebNov 6, 2016 · However, as mentioned here: A matrix is diagonalizable if and only if for each eigenvalue the dimension of the eigenspace is equal to the multiplicity of the eigenvalue. Meaning, if you find matrices with distinct eigenvalues (multiplicity = 1) you should quickly identify those as diagonizable. It also depends on how tricky your exam is.
