# Simple Algebra

(2n+1)(2n-1)(n+5)

I'm a little confused on how to do this one.

Any help would be greatly appreciated!!!

Thanks.

Thank you!!!

What are you trying to do? Multiply?

The first terms will make a difference of squares (a-b)(a+b)=a^2 - b^2

(4n^2-1)(n+5) Now multiply out these two terms.
