Worked through step by step. More factoring.

Answer
(x−4)(x+4)\boxed{(x - 4)(x + 4)}

Multiplying the factors back together using FOIL confirms they equal the original expression x2−16x^2 - 16.

Problem: Factor the expression x2−16x^2 - 16.

Steps

  1. Identify as a difference of squares
    x2−42x^2 - 4^2
  2. Apply the difference of squares formula (a2−b2=(a−b)(a+b)a^2 - b^2 = (a - b)(a + b))
    (x−4)(x+4)(x - 4)(x + 4)
