A= and O = Show A - O = 0 c d 0 0 at should be done to show A . 0 = 0? A. Right multiply A by A 1 B. Solve the equation AX = I, where X is a matrix of variables. C. Right multiply A by the scalar 0. D. Right multiply A by the 2 x 2 zero matrix, O. erform the operation above a +b + Simplify the expression above. Enter a 2 x 2 matrix. How has it been shown that A . O = O
