if A=diag[2,-5,9], B=diag[-3,7,14] and c= diag[4,-6,3] find 2A+B-C Share with your friends Share 0 Lalit Mehra answered this Given,Thus, 2A + B – C = diag [ –3, 3, 29] 0 View Full Answer Shruthy.v answered this 2A is [4,-10,18]..So 2A+B=[-1,-3,32]...subtracting C from this gives you,[-5,3,29]..So you get it as[-5,3,29]. 0 Aakanksha Bajaj answered this first u have to calculate 2Ai.e.diag[4,-10,18]after dat calculate 2A+Bi.ediag[-1,-3,32]after calculate 2A+B-Ci.ediag[-5,3,29] 0
