" If "A=[[3,1],[-1,2]]" and "I=[[1,0],[0,1]]

If A= [[5,2],[-1,2]] and I= [[1,0],[0,1]] show that (A-3I) (A-4I)=0

If A= [[6,2],[-1,3]] and I= [[1,0],[0,1]] show that (A-4I) (A-5I)=0

If A=[[3,1],[-1,2]], I=[[1,0],[0,1]] and O=[[0,0],[0,0]] , show that A^2-5A+7I=0 . Hence find A^(-1) .

If A = [[3,1],[-1,2]],I= [[1,0],[0,1]] and O = [[0,0],[0,0]] show that A^2-5A+7I=0 . Hence find A^(-1) .

Verify that the matrix equation A^2 - 4a +3I =0 is satisfied by the matrix A = [[2,-1],[-1,2]] , where I = [[1,0],[0,1]] and 0= [[0,0],[0,0]] ,

If A = [(5,2),(-1,2)] and I = [(1,0),(0,1)] show that (A - 3I) (A - 4I) = 0

If A=[(5,2),(-1,2)] and I=[(1,0),(0,1)] show that : (A-3I)(A-4I)=O

If I=[[1,0],[0,1]] and E=[[0,1],[0,0]] prove that (2I+3E)^3=8I+36E

if A=[[0,-2,-31,1,-40,-2,-1]] and I=[[1,0,00,1,00,0,1]]

If A = [(4,2),(-1,1)] and I = [(1,0),( 0,1)] prove that (A - 2I) (A - 3I) = 0
