(4x + 1)(4x - 1)
You can think of this like any other factoring problem.
16x2 - 1 is just like 16x2-0x -1, which shows you that the two terms that just have x in them cancel each other out. That means that they have the same coefficient, and opposite signs.
So looking at 16, it can be split into 4 and 4. These are the front coefficients of each section. Then, you know that to get a negative one, you have to have a positive one in one chunk, and a negative one in the other. Then, when you foil it out, the term with a single x is gone, and you prove that the answer is right.

What is 9x squared plus 16 when factoring?
9x^(2) + 16 DOES NOT factor. Remember ; two squared terms with a plus(+) between them DOES NOT factor However, two squared terms with a minus(-) between them DOES factor . Hence 9x^(2) + 16 = (3x)^2) + 4^(2) does NOT factor However, 9x^(2) - 16 = (3x)^2) - 4^(2) does factor to ( (3x - 4)(3x + 4) Note the two different signs.
