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

If A=[(1,x),(x^(2),4y)] and B=[(-3,1),(1,0)], adj(A)+B=[(1,0),(0,1)] then the values of x and y are

If A=[(1,2,3),(2,3,1)] and B=[(3,-1,3),(-1,0,2)], then find 2A-B.

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

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

(i) if A=[{:(1,0),(0,1):}],B=[{:(0,1),(1,0):}]and C=[{:(1,0),(0,1):}], then show that A^(2)=B^(2)=C^(2)=I_(2). (ii) if A=[{:(1,0),(1,1):}],B=[{:(2,0),(1,1):}]and C=[{:(-1,2),(3,1):}], then show that A(B+C)=AB+AC. (iii) if A=[{:(1,-1),(-1,1):}]and B=[{:(1,1),(1,1):}], then show that AB is a zero matrix.

If A=[{:(1,2),(1,1):}] and B = [{:(0,-1),(1,2):}] , then what is the value of B^(-1) A^(-1)

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