Question:medium

If \( \text{adj } B = \lambda I \) where \( |\lambda| = 1 \), then \( \text{adj} ((Q^{-1} B P^{-1})) \) =

Show Hint

For adjoints of transformed matrices, use the property \( \text{adj} (P^{-1} B Q^{-1}) = Q (\text{adj } B) P \), and adjust for inverses based on the given transformation.
