  • \\((x + 2)(x - 8)\\)
  • \\((x - 4)(x - 4)\\)
  • \\((x + 4)(x + 4)\\)
  • \\((x + 4)(x - 4)\\)

Explanation:

Identificar la expresión original

$$ x^2 - 16 $$

Aplicar la diferencia de cuadrados

$$ a^2 - b^2 = (a + b)(a - b) $$
$$ x^2 - 4^2 = (x + 4)(x - 4) $$

Answer:

  • (A) \((x + 2)(x - 8)\)
  • (B) \((x - 4)(x - 4)\)
  • (C) \((x + 4)(x + 4)\)
  • (D) \((x + 4)(x - 4)\) (Correct answer)
