How do you determine if a polynomial is the difference of two squares?

alexea,
If there are two ballons one in is 10m above the groung and rising 15m per minute the oter ballon is 150m above the ground and rising 20m per minute .in how many minutes will the ballons be at te same height?

PsyDAG,
First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.
Second, if the second balloon starts 140m higher than the first and has a higher rate of ascent, they will never be at the same height — unless they reach their upper limit in the atmosphere.
You have many typos. I assume that this true of your numerical data as well. Proofread your post to avoid typos.

Since this is not my area of expertise, I searched Google under the key words "polynomial difference two squares":

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps.
