|[1,3,5],[2,6,10],[31,11,38]|=0

Consider the determinant D=|[1,3,5],[2,6,10],[31,11,38]| On taking 2 outside the determinant from the second row, show that Delta=0

Consider the determinant D=|[1,3,5],[2,6,10],[31,11,38]| Evaluate Delta directly by expanding along 2^(nd) row and see that the answer is the same .
