Question 16 Check whether (l + m + n) is a factor of the determinant |(l + m) (m + n) (n + l) n l m 2 2 2| or not. Give Reason | (l + m n 2 m + n l 2 n + l m 2 )| Applying ๐‘…1โ†’ ๐‘… 1 + ๐‘…2 | (l + m + n n 2 m + n + l l 2 n + l + m m 2 )| Taking (๐‘™+๐‘š+๐‘›) common from ๐‘…_1 (l + m + n) | 1 n 2 1 l 2 1 m 2 ] Since (๐‘™+๐‘š+๐‘›) is multiplied outside, it means that is a factor of the determinant
