Which of the following is not a factor of x2 + 24x - 144?

  1. 3

  2. 8

  3. 9

  4. 12

The correct answer is: 3

The factors of x2 + 24x - 144 are (x+12)(x-12). Since 3 is not a factor of 144, it cannot be a factor of x2 + 24x - 144. Choices B, C, and D are all factors of 144 and therefore can be included in the factorization.
