Thread: Binomial Theorem with coefficients

I can get the binomial theorem to work just fine when doing (a+b)^n but it becomes a problem as soon as I put coefficients, e.g.: (2a+3b)^n

Why? What is the difference and how do I calculate with coefficients?

Well, there's no difference.





Um, did this help?

Consider .[1]

Suppose we are given: .

Then we have: .


Substitute into [1]:

n . . . . . . . .

It did indeed help. I was being silly and kept writing a^(n-k)*b^k even though I had coefficients.

Thanks a lot!

Where do I find a guide to write math like you guys do?

You can use LaTeX tags. Go to this tutorial.

[tex] x = \neg A\cdot \neg B\cdot C + \neg A\cdot B\cdot \neg C + \neg A\cdot B\cdot C + A\cdot \neg B\cdot \neg C [/tex] gives
Click on the “go advanced” tab. On the toolbar you will see clicking on that give the LaTeX wraps, [tex] [/tex]. The code goes between them.

You can also click on Reply with Quote. That will allow you to ‘steal’ any code that you see that you like.
