Respuesta:

Explicación paso a paso:

1. x² - y² = (x - y)(x + y)

2. a² - 1 = a² - 1² = (a - 1)(a + 1)

3. a² - 4 = a² - 2² = (a - 2)(a + 2)

4. 9 - b² = 3² - b² = (3 - b)(3 + b)

9. 4a² - 9 =  (2a)² - 3²

10. 25 - 36$x^{4}$ = 5² - (6x²)² =  (5 - 6x²)(5 + 6x²)

15. $a^{10} - 49b^{12}$ = ($a^{5}$)² - (7$b^{6}$ )² = ($a^{5}-7b^{6}$)($a^{5} + 7b^{6}$)

19. 196x²$y^{4}$ - 225$z^{12}$ = (13xy²)² - (15$z^{6}$)² = (13xy² - 15$z^{6}$)(13xy² + 15$z^{6}$)

20. 256$a^{12}$ - 289$b^{4}m^{10}$ =  (16$a^{6}$)² - (17b²$m^{5}$)² = (6$a^{6}$ - 17b²$m^{5}$)(6$a^{6}$ + 17b²$m^{5}$)

21. 1 - 9a²$b^{4}c^{6}d^{8}$ = 1² - (3a$b^{2}c^{3}d^{4}$)² = (1 - 3a$b^{2}c^{3}d^{4}$)(1 + 3a$b^{2}c^{3}d^{4}$)
