For those of you who read this question, thanks. Some asked, "what is the number that they give you?" Well, that's it. there is no number or any other information for me to go on. For those of you who want to give it a shot, here it is again: "A number has only 3 digits, all in the ones period. What are the digits in the thousands' period?"

I interpret the beginning part of the question to mean that this is a 3 digit number. But how can they all be in the ones place? The only answer I can come up with is 0 becasue if the number is 002, isn't that a 3 digit number with another 0 in the thousands place? However, the end of the question asks, "what are the digits (plural) in the thousands place?" That seems to debunk my answer of 0.

Please help, thanks!

Or not simple. It doesn't really matter, just someone help me!

I haven't taken an algebra course for a few years (I've been on a gemoetry course for about 2) and now I need to know how to factor for my homework.

Here are the questions:

1. 25x^2-16y^2
2. 3x^2+20x+25
3. 3x^3-39x^2+120x

Even if you can't explain them, if you culd list the steps to get the answer I'll be able to figure it out. Thank you so much!
