" 4.If "A=[[3,1],[-1,2]]" and "I=[[1,0],[0,1]]" ,then the correct statement is "

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

A=[{:(0,0,-1),(0,-1,0),(-1,0,0):}] ,the correct statement is ......

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)] and I=[(1,0),(0,1)] find 'k' so that A^(2)=5A+kI .

Let A=[[0, 0 ,-1],[0,-1,0],[-1,0,0]] . The only correct statement about the matrix A is

Statement-1 (Assertion and Statement- 2 (Reason) Each of these questions also has four alternative choices, only one of which is the correct answer. You have to select the correct choice as given below. Statement -1 If A= [[1,-1,-1],[1,-1,0],[1,0,-1]] then A^(3) + A^(2) + A= I Statement - 2 If det (A-lambdaI) = C_(0) lambda^(3) + C_(1) lambda^(2) + C_(2)lambda + C_(3) = 0. then C_(0) A^(3) + C_(1)A ^(2) + C_(2)A + C_(3)I = O.
