यदि `(If)= A [-1,-1),(2,-2)]`, दिखाएँ की `A^(2) +3A +4I_(2) = O ` तथा इससे`A^(-1)` निकले ।

Find the inverse of each of the matrices given below : If A=[(-1,-1),(2,-2)] " show that " A^(2)+3A+4I_(2)=O and " hence find "A^(-1) .

If A=[(2,-1),(-1,2)] , then show that A^(2) -4A +3I=O .

If A = [(2, -2),(-3,1)] , then show that ( A + I) ( A - 4 I) = O

If A = [(1,2,2),(2,1,2),(2,2,1)] then show that A^(2)-4A-5I = O .

If A=[[5,3],[-1,-2]] , show that A^(2)-3A-7I_(2)=O_(2) Hence find A^(-1) .

i^4 (1) 0 (2) -1 (3) 1 (4) 2

If A=[{:(3,1),(-1,2):}] , show that A^(2)-5A+7I=O .

If A = [[3,1],[-1,2]] , show that A^2-5A +7I = O

If A = {:[(1,2,3),(3,-2,1),(4,2,1)] , then show that : A^2 - 23 A - 40 I ne O

If A = [[1,2,3],[3,-2,1],[4,2,1]] , then show that A^3 - 23A - 40I = O
