En resumen
(A + B)(A - B) = A² - B² A = (2 a + 3b) (2a - 3b) (2a)² - (3b)² = 4a² - 9b² B = (4 a + 6b) (4a - 6b) (4a)² - (6b)² = 16a² - 36b² C = (6a + 9b) (4a + 6b) 24a² + 72ab + 54b².

(A + B)(A - B) = A² - B²
A = (2 a + 3b) (2a - 3b)
(2a)² - (3b)² = 4a² - 9b²
B = (4 a + 6b) (4a - 6b)
(4a)² - (6b)² = 16a² - 36b²
C = (6a + 9b) (4a + 6b)
24a² + 72ab + 54b².
