Show that the matrix, `A=[1 0-2-2-1 2 3 4 1]`satisfies the equation,`A

1.	Show that the matrix, `A=[1 0-2-2-1 2 3 4 1]`satisfies the equation,`A^3-A^2-3A-I_3=O`. Hence, find `A^(-1)`.
Answer» `A^(-1)=[(-9,-8,-2),(8,7,2),(-5,-4,-1)]`

Find the inverse of each of the matrices given below : Compute `(AB)^(-1) when A=[(1,1,2),(0,2,-3),(3,-2,4)] and B^(-1)=[(1,2,0),(0,3,-1),(1,0,2)]`. Find `A^(-1).
Find the inverse of each of the matrices given below : Obtain the inverse of the matrics `[(1,p,0),(0,1,p),(0,0,1)] and [(1,0,0),(q,1,0),(0,q,1)]`. And, hence find the inverse of the matrix`[((1+pq),p,0),(q,(1+pq),p),(0,q,1)]`. Let the first two matrices be A and B. Then, the third matrix is AB. Now, `(AB)^(-1)=(B^(-1)A^(-1))`
Find the inverse of each of the matrices given below : Show that the matrix `A=[(-8,5),(2,4)]` satisfies the equation `x^(2)+4x-42=0` and hence find `A^(-1)`.
