For the matrix `A=[3 2 1 1]` , find the numbers `a` and `b` such that `A^2+a A+b I=O` . Hence, find `A^(-1)` .

For the matrix A=[[3,21,1]], find the numbers a and b such that A^(2)+aA+bI=O

For the matrix A=[{:(3,2),(1,1):}] , find the numbers a and b such that A^2+aA+bI=O

For the matrix A = [[3,2],[1,1]] , find the numbers a and b such that A^2+aA+bI = O

For the matrix A=[3211], find the numbers a and b such that A^(2)+aA+bI=O. Hence find A^(-1) .

For the matrix A= [[3,2],[1,1]] , find the numbers a and b such that A^2+aA+bI=O .

For the matrix A=[{:(2,1),(3,0):}] , find the numbers 'a' and 'b' such that A^(2)+aA+bI=O . Hence , find A^(-1) .

For the matrix A={:[( 3,2),( 1,1) ]:} . Find the numbers a and b such that A^(2) +aA+bI =O.
