I was just adding something to my method for evene. See my post #4. You have the same answer I do.

I do not thickhead noticed that.

In how many ways can you arrange them in a row

In arrangements order counts. _ _ c g _ _ _ _ and _ _ g c _ _ _ _ are different.

Who is this mathaholic guy? I do not remember him.

Yes, even a bumpkin can understand. That is the problem, he is an expert, not a bumpkin.

You look a little thin, have you been eating?

#8 Re: Help Me ! » Find the roots of the following polynomial » Yesterday 13:42:42

Here is one way by completing the cube: … 1038166535

And there is a formula in terms of the coefficients.

But as I have been saying to evene and corrupted, it is much easier to do numerically.

Hee, hee, you are right Lehona, for some reason everyone looked only for integer solutions. There are 6 solutions in all.

#11 Re: Help Me ! » Lagrange Interpolation in a finite Field » Yesterday 10:28:57

Yes, MathS.E. might be able to help.

I agree, I do not know what is going on there.

Please post the link when you post there, I would like to follow the discussion and welcome to the forum.

#12 Re: Help Me ! » Lagrange Interpolation in a finite Field » Yesterday 10:22:56

I was afraid you would say that. It looks like the coefficients have been reduced by  mod 8? Unfortunately, I do not remember how to interpolate with a mod. I am reading up on it but in the meantime have you tried the SE?

#13 Re: Help Me ! » Lagrange Interpolation in a finite Field » Yesterday 10:03:04

I'm really at a loss here, as these polynomials don't seem to form any relation with the given table?

I do not see the relationship either...

Do you have any example of how those interpolating polynomials were formed? What was the data?

Not to be funny but can you say something about "something".

#16 Re: Help Me ! » solve » Yesterday 07:03:14


Due to teacher complaints about cheating and copyright violation we are restricted in how much and what type help we can give for homework questions.

Do you have some work of your own that I can improve or help on? If you show some work, some effort, then you can be helped. It is as simple as that.

#17 Re: Help Me ! » Rearranging students in a class » Yesterday 06:25:15

I think that overcounts. You were close with your first answer but overcounted there too. Assuming that the six remaining students are distinguishable I am getting 14 * 6! = 10080

That is one dream I have never had.
