if for a matrix `A, A^2+I=O`, where I is the identity matrix, then A equals

If for a matrix A,A^(2)+I=O where I is the indentity matrix, then A=

(C) equal to In1f for a matrix A, A? +| =0 where I is the identity matrix, then A equale1 0(A) o 1© @ :?-1 01(C)1 1c1 27[o -1

If for a matrix A,A^2+I=0, where I is an identity matrix then A equals (A) [(1,0),(0,1)] (B) [(-1,0),(0,-1)] (C) [(1,2),(-1,1)] (D) [(-i,0),(0,-i)]

Matrix A such that A^(2)=2A-I , where I is the identity matrix, then for n ge 2, A^(n) is equal to

Matrix A such that A^(2)=2A-I , where I is the identity matrix, then for n ge 2, A^(n) is equal to

Matrix A such that A^(2) = 2A - I , where I is the identity matrix, then for n ge 2, A^(n) is equal to a) 2^(n - 1) A - (n - 1) I b) 2^(n - 1)A - I c) n A - (n - 1) I d) nA - I

If A is skew symmetric matrix, then I - A is (where I is identity matrix of the order equal to that of A)
