Miranda -This is a pretty simply factoring problem once you notice that it contains the "difference of perfect squares"  What do I mean by that?  Here is an example:Because the values to the left of the equal sign are the difference (note: "difference" just means subtraction) of perfect squares, we can use the factors to the right of the equal sign.  Make sense?Now for your problem:Again, you have the difference of perfect squares and you can use the formula above.Hope that helped
