If A^2 – A + I = 0, then the inverse of A is - Sarthaks eConnect ...

WebIf A is nilpotent, then its only eigenvalue is 0, so I + A is invertible. Is there a closed-form solution? I believe not. Basically, a closed-form expression of ( I + A) − 1 using A and A − … WebIf for the non-singular matrix A,A2 = I, then find A−1 . 3870 82 Determinants Report Error A A B I C O D None of these Solution: Given, A2 = I Since, A is non-singular matrix ∴ ∣A∣ = 0,so,A−1 exists. Multiplying by A−1 on both sides, we get A−1 (A2) = A−1 (I) ⇒ (A−1A)A = A−1 ⇒ I A = A−1 (∵ A−1A = I) ∴ A−1 = A (∵ I A = A) WebI f A 2−A+I=0, then the inverse ofA is A I - A B A-I C A D A + I Easy Solution Verified by Toppr Correct option is A) Given, A 2−A+I=0 Multiply by A −1 A −1AA−A −1A+A −1I=0 IA−I+A −1=0 A −1=I−A Solve any question of Matrices with:- Patterns of problems > Was this answer helpful? 0 0 Similar questions Let A=⎣⎢⎢⎡121−111 1−31 ⎦⎥⎥⎤ and how do you uninstall microsoft bing
