Question

Question 3(iv)
Add the following:
(iv) $l^{2} + m^{2}, m^{2} + n^{2}, n^{2} + l^{2} + 2 l m + 2 m n + 2 n l$

Open in App

Solution

(iv) $l^{2} + m^{2}, m^{2} + n^{2}, n^{2} + l^{2}, 2 l m + 2 m n + 2 n l$
$S u m = l^{2} + m^{2} + m^{2} + n^{2}$ $+ l^{2} + n^{2} + 2 m l + 2 m n + 2 n l (a d d i n g l i k e t e r m s)$

Hence, the sum is
$2 (l^{2} + m^{2} + n^{2} + l m + m n + n l)$
