Answer 1

@mathmale

Answer 2

Ask yourself: do the left two terms, 2mn-3m, have anything in common with the right two terms, 8n-12 ?

Answer 3

i dont think so.. i dont know

Answer 4

Have you done "factoring by grouping" before? or at least seen examples in your study material?

Answer 5

explain

Answer 6

My goal, and preference, is to build upon what you already know, instead of explaining something from scratch.

Please look at the first two terms: 2mn-3m . What have these two terms in common?

Answer 7

they both have m

Answer 8

Right. Please re-write 2mn-3m by factoring out the m.

Answer 9

umm ..

Answer 10

What's 2mn with the 'm' separated from the rest of this term? Re-write 2mn in factored form.

Answer 11

omg i was about to do it differently

Answer 12

If you have another way, by all means demo your way first.

Answer 13

no thanks

Answer 14

What's 2mn with the 'm' separated from the rest of this term? Re-write 2mn in factored form.

Answer 15

2mn = m( ) please finish factoring this.

Answer 16

i was thinking the answer was -1n..

Answer 17

2mn = m( ) please finish factoring this.

Answer 18

What you're doing is essentially dividing 2mn by m. What's the result?

First, write m (which you have factored out). Next, inside parentheses, write what's left of 2mn.

Answer 19

What is 2 divided into 10?

Answer 20

I'm happy to help, but really need and expect your involvement. Return the best answers you can; if they're wrong, we'll review and work on the material further. Please respond.

Answer 21

im not on that anymore

Answer 22

Sounds as though you may need a review of basic division and factoring. Also, if someone is trying to help you, the least you could do is respond, and respond promptly.

Answer 23

well excuse me if im trying to do my work

Answer 24

If you post a question here, those who help you expect that you'll demonstrate that you're trying to do your work by sharing what you have done.

Answer 25

umm no i dont want people expecting im dumb so..

Answer 26

Why not change your attitude to one more constructive and positive, and get back to work?

Answer 27

im trying

Answer 28

Prove it. Show some work, please.

Answer 29

umm no

Answer 30

Looks like you just want a verbal fight. May I suggest you stop this now, and either show some effort / post some work, or come back when you're ready to work.

Answer 31

excuse me im not looking for anything, that is rude to try to tell me what i want.

Answer 32

Mathmale was not being rude. He was explaining how the site works. Pleas read this:
http://openstudy.com/code-of-conduct

See the part on, "OpenStudy values the Learning process - not the ‘Give you an answer’ process" where it states "Have homework problems? We can help you - as long as you are looking to learn how to get your solution (and not just the answer)." and then there is "Don't devalue the question/answer process!" where it adds "Don't provide someone with just the answer - explain the process, and help guide them through understanding the problem."

What all of this means is that users need to participate and be active learners. If you are not interested in being an active learner, this is the wrong site to use. However, if you are willing to participate in your learning, this site can help you do better.

Answer 33

dont talk to me

Answer 34

and i didnt say he was supposed to give me the answer and in my defense he was being rude and tried to get me suspended so goodbye.

Answer 35

He did not try to get you suspended, he suspended you. You then evaded that suspension, which makes you an automatic candidate for being banned permanently.

mathmale is a moderator. I am a moderator. We are part of the group that suspends people.

What mathmalle was trying to explain about web courtesy is pretty simple. If you are going to change to another topic, all you had to do was post, "Hey, thanks, I get it. I am moving on to another question." Why? Because if you don't tell someone you are moving on, they may sit here and try to keep helping you. It is pretty rude to just leave people hanging like that.

As for your statement, "dont talk to me" I hate to inform you but there is no way to stop a moderator from talking to you. We can not be blocked in the message system, etc. The reason why is simply. One of our tasks is to pass on the purpose, rules, and culture of the site. If people are able to block us, it can prevent that. We are specifically authorized to keep communicating with people in an effort to bring them in line with how this site is meant to be used.

As I said before, if you are willing to work with the site in a polite way that leads to a better understanding, great. However, if you keep that chip on your shoulder and continue to act impolitely, you will just have more and more issues until you are banned. It really is that simple of a choice and it is yours to make.
