(12-4a²)² =
(12-4a²)(12-4a²) =
12(12 - 4a²) - 4a²(12 - 4a²) =
(12)(12) + (12)(-4a²) + (-4a²)(12) + (-4a²)(-4a²) =
144 - 48a² - 48a² + 16a^4 =
144 - 96a² + 16a^4
esta es la repuesta,

(12-4a²)(12-4a²) =
12(12 - 4a²) - 4a²(12 - 4a²) =
(12)(12) + (12)(-4a²) + (-4a²)(12) + (-4a²)(-4a²) =
144 - 48a² - 48a² + 16a^4 =
144 - 96a² + 16a^4
