SpletYou have to show that any matrix that satisfies the equation A 2 + 2 A + I = 0 is invertible. – 5xum Mar 2, 2014 at 22:49 Add a comment 5 Answers Sorted by: 4 The inverse of A is almost certainly not A. You have A 2 + 2 A = − I, or A ( A + 2 I) = − I. Multiplying by − 1 you get A ( − A − 2 I) = I Hence the inverse of A is − A − 2 I. Share Cite Splet6.
