You can put this solution on YOUR website!
q%5E2+-+16+=+%28q%2B4%29%28q-4%29
You can either recognize that as a difference of two squares, or factor it with reverse FOIL. Now the problem is simple.


%28q%2B4%29%28q-4%29%2F%28q%2B4%29%28q%2B4%29+=+%28q-4%29%2F%28q%2B4%29
You cannot solve it further, because it isn't an equation. But now it is simplified.

If you need help understanding math so you can solve these problems yourself, then one on one online tutoring is the answer ($30/hr). If you need faster solutions with guaranteed detailed answers, then go with personal problem solving ($3.50-$5.50 per problem). Contact me at fcabanski@hotmail.com
