    Let's see,

    1. (20 - 3) ^2

    (20 - 3) ^2 = 20 - 3 = 17 * 17 = 289

    2. (20 - 3) (20 + 3)

    (20 - 3) (20 + 3) = 20 - 3 = 17, 20 + 3 = 23, (17) * (23) = 391.

    3. (20 - 9) (20 + 9)

    (20 - 9) (20 + 9) = 20 - 9 = 11, 20 + 9 = 29, (11) * (29) = 319.

    4. (20 + 3) ^2

    (20 + 3) ^2 = 20 + 3 = 23 * 23 = 529

    Answer: #2, (20 - 3) (20 + 3)
