If `A[(1, 0, 0),(x, 1, 0),(x, x, 1)] and I=[(1, 0, 0),(0,1,0),(0,0,1)]`, then `A^(3)-3A^(2)+3A` is equal to

Let I=((1,0,0),(0,1,0),(0,0,1)) and P=((1,0,0),(0,-1,0),(0,0,-2)) . Then the matrix p^3+2P^2 is equal to

Let I = [{:(1, 0, 0),(0 ,1, 0),(0,0,1):}] and P = [{:(1, 0, 0),(0 ,-1, 0),(0,0,-2):}] . Then the matrix p^(3) + 2P^(2) is equal to

The inverse of [(1,a,b),(0,x,0),(0,0,1)] is [(1,-a,-b),(0,1,0),(0,0,1)] |then x =

If {:A=[(1,2,x),(0,1,0),(0,0,1)]andB=[(1,-2,y),(0,1,0),(0,0,1)]:} and AB=I_3 , then x + y equals

If A=|[1,0,1],[0,1,2],[0,0,4]| then |3A|

If A=|{:(1,0,0),(0,1,0),(0,0,1):}|" and A"=[{:(0,-3,4),(1,2,3),(0,5,5):}]," then find "(I-A)^(-1)

If A=((1,0,0),(0,2,1),(1,0,3)) then (A-I)(A-2I)(A-3I)=

If A = {:((1,-1),(1,2)):} and I={:((1,0),(0,1)):} then 3A^(-1) is equal to :
