WebIf A2 − A+ I = O, then the inverse of the matrix A is 2069 97 WBJEE WBJEE 2009 Matrices Report Error A A−I B I − A C A+I D A Solution: Given, A2 −A+I = O ⇒ A2 −A = −I ⇒ A2A−1 −AA−1 = −I A−1 ⇒ A−I = −A−1 ⇒ A−1 = I − A Web16 sep. 2024 · Take times the first row and add to the second to get Now take times the second row and add to the first to get Writing in terms of variables, this says and Now solve the second system, to find and You will find that and . If we take the values found for and and put them into our inverse matrix, we see that the inverse is

If A = 1 0 0 0 1 1 0 - 2 4 ,6A^-1 = A^2 + cA + dI , then (c,d) is ...

WebYou 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.
