उत्तर
The given expressions are written in separate rows, with like terms one below the other, and then the addition of these expressions is as follows:
l2 + m2
+ m2 + n2
l2 + n2
+ 2lm + 2mn + 2nl
__________________________________
2l2 + 2m2 + 2n2 + 2lm + 2mn + 2nl
Thus, the sum of the given expressions is 2l2 + 2m2 + 2n2 + 2lm + 2mn + 2nl.
