Answer 12

If you want to know, a difference in squares pattern works when you find the square root of both terms and have two binomials, one with a + and one with a -.
(x + 3)(x - 3) = x^2 + 3x - 3x - 9 = x^2 - 9
See how the middle terms cancel out? Your problem is the same, except that the x is the second term.
