here a matrix problem ...asked in 2005 cbse exam ....I took a approach tha i split the last column and further solve it ....but after two step I got struck and answer was not coming

1st step ...split the 3rd column
And then take b,c and a common from r1,r2,r3 from 1stdet and c,a and b from r1,r2,r3 from second determinant and then r1->r1-r3, r2->r2-r3 for both det.
