See, do you know DIVISION BY 0 is not possible??

anonymous · Answer

Yeah!

anonymous · Answer

So, can you figure it out or still in problem??

anonymous · Answer

No i can't. I'm not any good at this stuff.

anonymous · Answer

First term there is $3b^2$, right??

anonymous · Answer

Yes

anonymous · Answer

So, what will you get when you put b = 0 here??

anonymous · Answer

Would you multiply 3 and b together? But if you do that then you'll get 0.

anonymous · Answer

Yep,for first term you will get 0..
Now second term is : 13b

when you will put b = 0, here what will you get??

anonymous · Answer

Yep, Good..

Now look at third term:

You have : $\large \frac{4}{b}$

Now put b = 0, and tell me what did you get?

So now you are posting the questions from this quiz individually, I see so that it cannot be identified as a quiz.

anonymous · Answer

@Mertsj but he just said that he or she wants the understanding of how to solve these questions, and he or she does not want straight answer, it is a good sign I think..

anonymous · Answer

Well 4/0 can't be divided so it be 0.

anonymous · Answer

How it can be 0??

See, if have told you above that DIVISION BY 0 is avoided..

So if you put b = 0 here then you will get:
4/0 = Undefined..

anonymous · Answer

So undefined value is the value for which the expression becomes Undefined..

anonymous · Answer

@Mertsj I told you i don't know how to work this kind of problems out, i'm only asking this one question not all 10. Ok, @waterineyes i don't know what undefined means is it like no solution or something.

anonymous · Answer

It can be..

mertsj · Answer

And I told you that quizzes are for the teacher to find out what you have learned...not for you to get someone else to explain the problems and confirm answers so you can get a grade that gives the teacher false information because it doesn't reflect what you know.

mertsj · Answer

If you truly want to learn how to do the problems, I'm sure your course has explanations that are just as good as any you will get here.  Go back, read, look at the examples, and learn.

anonymous · Answer

I've tried that it doesn't tell you how to do it, it doesn't really have good info.
