Determinant of a Matrix - Math is Fun

WebSolution : In order to show any two rows or columns are same, let us multiply "a", "b" and "c" by the 1 st, 2 nd and 3 rd row respectively. Now we may factor abc from 2 nd and 3 rd column respectively. Since column 1 and 2 are identical, the value of determinant will become 0. So, we get (abc) 2 (ab + bc + ca) (0). Hence the answer is 0.
