Thanks guest,

It is great to see that my post sparked some interest. :)

The first one is great.

You did make one small error though. (It is a very common error all through mathematics)

Can you find it?

The second one is also good. I haver not checked it I am just impressed that you did it. I assume it is correct since you did it with a program.

However I do not understand your formula. How can 6+3- a positive number =28

mmmm

Oh maybe my detective work has worked.... do you mean ???

nCr

where n=6+3-1 [Exponent of polynomial + number of terms - 1]

and r = 6 [exponent of polynomial]

So that is 8C6 = 28 Bingo

So for a nomal cubic binomial (a+b)^3 There would be (3+2-1)C3 = 4C3 = 4 terms.

Das ist Ausgezeichnet!
