Вот ответ. Тут правильно

Answer 2

Expanding each of the given expressions, we have:

1. (x - 5)(x + 5) = x^2 - 25
2. (6 - y)(6 + y) = 36 - y^2
3. (a - 7)(a + 7) = a^2 - 49
4. (1 - c)(1 + c) = 1 - c^2
5. (m - 4)(m + 4) = m^2 - 16
6. (n - 2)(n + 2) = n^2 - 4
7. (x - 9)(9 + x) = -81 + x^2
8. (11 - d)(d + 11) = -d^2 + 121
9. (4 + b)(b - 4) = -b^2 + 16
10. (a + 12)(12 - a) = -a^2 + 144
11. (c - 3)(3 + c) = -c^2 + 9
12. (8 - b)(b + 8) = -b^2 + 64

Please note that the order of the terms in the expansion may be different from what you provided, but the resulting expressions are equivalent.
