Формулы сокращенного умножения:
(a + b)² = a² + 2ab + b²
(a - b)² = a² - 2ab + b²
1. (n + 6)² = n² + 2·6n + 6² = n² + 12n + 36
2. (13h + 1)² = (13h)² + 2·13h + 1 = 169h² + 26h + 1
3. (4 - 3y)² = 4² - 2·4·3y + (3y)² = 16 - 24y + 9y²
4. (2k - 8)² = (2k)² - 2·2k·8 + 8² = 4k² - 32k + 64
5. (3c + 7d)² = (3c)² + 2·3c·7d + (7d)² = 9c² + 42cd + 49d²
6. (9a + t)² = (9a)² + 2·9a·t + t² = 81a² + 18at + t²
7. (k - 8)² = k² - 2·k·8 + 8² = k² - 16k + 64
8. (5 - 7m)² = 5² - 2·5·7m + (7m)² = 25 - 70m + 49m²
9. (13p - 3)² = (13p)² - 2·13p·3 + 3² = 169p² - 78p + 9
10. (2f - 10a)² = (2f)² - 2·2f·10a + (10a)² = 4f² - 40af + 100a²
