Matrices A and B will be inverse of each other only if (A) AB=BA (B) AB=BA=0 (C) AB = 0, BA=I (D) AB=BA = I

Matrices A and B will be inverse of each other oolly if (A) AB=BA(B)AB=BA=0(C)AB=0,BA=I(D)AB=BA=I

If A=[(1,0),(2,0)] and B=[(0,0),(1,12)] then= (A) AB=0, BA=0 (B) AB=0,BA!=0 (C) AB!=0,BA=0 (D) AB!=0,BA!=0

If A=[(1,0,),(2,0)] and B=[(0,0),(1,12)] then= (A) AB=0, BA=0 (B) AB=0,BA!=0 (C) AB!=0,BA=0 (D) AB!=0,BA!=)

If A and B are square matrices of the same order then (A+B)^2=A^2+2AB+B^2 implies (A) AB=0 (B) AB+BA=0 (C) AB=BA (D) none of these

if A and B are symmetric matrices of same order then (AB-BA) is :

If AB=A and BA=B, then B^2 =

If A and B are two matrices such that AB=B and BA=A then A^2+B^2= (A) 2AB (B) 2BA (C) A+B (D) AB

If A and B are symmetric matrices of same order, then AB-BA is a
