Answer 4

The above answers sound fine, but I don't think they help you. You need to look at the given equation to be of the form (a^2 - b^2). Factors of it are (a-b)(a+b). In the specific example, you need to find the number whose square is 64. Said another way, the square root of 64. It turns out to be 8. So, you have (8^2-x^2). The factors therefore will be (8-x)(8+x).
