Expanding and simplifying the expression (-2m-7n)^2, we get:
(-2m-7n)^2 = (-2m-7n)(-2m-7n)
= (-2m)(-2m) + (-2m)(-7n) + (-7n)(-2m) + (-7n)(-7n)
= 4m^2 + 14mn + 14mn + 49n^2
= 4m^2 + 28mn + 49n^2
Therefore, the expanded and simplified expression is 4m^2 + 28mn + 49n^2.
(-2m-7n)^2 = (-2m-7n)(-2m-7n)
= (-2m)(-2m) + (-2m)(-7n) + (-7n)(-2m) + (-7n)(-7n)
= 4m^2 + 14mn + 14mn + 49n^2
= 4m^2 + 28mn + 49n^2
Therefore, the expanded and simplified expression is 4m^2 + 28mn + 49n^2.
