Question: 277
11. If x is an odd number, which one of the following expressions is an even number?
- A. x(x + 8)
- B. (x + 2)(x – 4)
- C. x2 – 2
- D. x2 – x
Correct Answer: D
Explanation:
D
As the square of an odd number is odd, and the difference between two odd numbers is even, choice (D) will yield an even number when x is odd.
Plug an odd value for x, such as x = 3, into the answer choices. Only choice (D) is even.
