Add the following expressions:
$I^{2} + m^{2} + n^{2}, I m + m n, m n + n I + I m$

Open in App

Solution

$1^{2} + m^{2} + n^{2}, 1 m + m n, m n + n l, n 1 + 1 m$
On adding the expressions, we have
= $1^{2} + m^{2} + n^{2} + 1 m + m n + m n + n 1 + n 1 + 1 m$
= $1^{2} + m^{2} + n^{2} + 21 m + 2 m n + 2 n 1$
