" 2.यदि "A=[[1,2,2],[2,1,2],[2,2,1]]" So check that "A^(2)-4A-5I=0

If A=[[1,2,2],[2,1,2],[2,2,1]] , verify that : A^2-4A-5I=O

If A =[[1,2,2],[2,1,2],[2,2,1]] then prove that A^2-4A-5I=0 .

A=[[1,2,2],[2,1,2],[2,2,1]] , then show that A^2-4A=5I_3

(b) answer the following questions: 1. if A=[[1,2,2],[2,1,2],[2,2,1]] , then show that A^2-4A-5I_3=0

If A=[[1,2,22,1,22,2,1]], then prove that A^(2)-4A-5I,=O

If A=[[1,2,2], [2,1,2],[2,2,1]] then A^(2)-5I=

Show that the matrix A=[[1,2,2],[2,1,2],[2,2,1]] satisfies the equation A^2-4A-5I_3=0 and hence find A^(-1)

If A [{:(1,2,2),(2,1,2),(2,2,1):}] , show that A^2 -4A -5I =0

If A= [[1,2,2],[2,1,2],[2,2,1]] , find A^2-4A-5I=O

If A = [(1,2,2),(2,1,2),(2,2,1)] then show that A^(2)-4A-5I = O .
