If `A=[[2,0,1],[2,1,3],[1,-1,0]]` , then find value of `A^(2)-5A+6I`

If A=[[2,0,1],[2,1,3],[1,-1,0]] , then find (A^(2)-5A)

If A=[(2,0,1),(2,1,3),(1,-1,0)] , then find (A^(2)-5A)

if A=[[1,2,22,1,22,2,1]] then find the value of A^(2)-4A+5I_(3) then find the value of

If A=[[2,a,-3] , [0,2,5] , [1,1,3]] then,find the value of a for which A^(-1) exists.

If A=[{:(2,0,1),(2,1,3),(1,-1,0):}] . find A^(2)-5A+6I and hence , find a matrix X such that A^(2)-5A+6I+X=O .

If A=[[1,2,5],[3,4,6]] and B=[[4,0],[2,1]] then find the value of AB.

If A = [(-1,2),(3,1)],B=[(1,0),(-1,0)] then the value of 2A+B+2I=

If A=[(2, 0, 1 ),(2, 1, 3),( 1,-1, 0)] , find A^2-5A+4I and hence find a matrix X such that A^2-5A+4I+X=O .

If A=[[1,2,5],[3,4,6]] and B=[[4,0],[2,1],[1,1]] then find AB
