1B> Find the coefficient of (1+x)^7 (1-x) ^8

Thanks for your help :)

**drwls**, Monday, August 4, 2008 at 8:45am1A> There is no x^(2r) term. Do you mean the x^2 term coefficient?

1B> Which coefficient do you want? You only ask for one, but there are 15 of them.

This web site will tell you how to use the binomial theorem to get the coefficients of polynomials:

in the second part, i wanna find the coefficient of x^7

**Brandon**, Monday, August 4, 2008 at 2:47pmWe did this in Algebra III, but I can not remember how to do it. What course does this fall under for you, Tommy? Is there a section in your textbook that mentions this, possibly as an extension or application or some such extra bonus material?

I learnt the binomial theorem, the (r+1) term theorem, how to expand the binomial expression using the the pascal triangle.
