1. Recognize the formula for the square of a binomial:
(a+b)^2 = a^2 + 2ab + b^2
2. Let \( a = 7m \) and \( b = 6n \).
3. Calculate \( a^2 \):
(7m)^2 = 49m^2
4. Calculate \( 2ab \):
2 \cdot (7m) \cdot (6n) = 84mn
5. Calculate \( b^2 \):
(6n)^2 = 36n^2
6. Combine these results:
49m^2 + 84mn + 36n^2
Answer:
49m^2 + 84mn + 36n^2
