Let's find value of :
`a (m + n) + b ( n + l) + c(l + m) if a = lx + my +n, b = mx + ny +l, c = nx + ly +m`

If x/(lm - n^2) = y/(mn - l^2) = z/(nl - m^2) the value of lx + my +nz will be

If x/(lm - n^(2)) = y/(mn - l^(2)) = z/(nl - m^(2)) , then show that lx + my + nz = 0 .

Let's find L.C.M of the following. (a) 36, 60, 72

If the vectors vec a, vec b, vec c are non-coplanar and l,m,n are distinct real numbers, then [( l vec a + m vec b + n vec c) (l vec b + m vec c + n vec a) (l vec c + m vec a + n vec b )] = 0, implies (A) lm+mn+nl = 0 (B) l+m+n = 0 (C) l^2 + m^2 + n^2 = 0
