Q34 of 124 Page 186

Give an example of three matrices A, B, C such that

AB = AC but B ≠ C.


Given : AB = AC and B ≠ C.


To Find : matrix A and B


Formula used :



Where cij = ai1b1j + ai2b2j + ai3b3j + ……………… + ainbnj


Let A = , B = and C =


B ≠ C


AB = =


AB = = 0


AC = =


AC = = 0


AB = AC = 0


A = , B = and C =
