1. ## help with factorising

Hello! I'm having a bit of trouble working out how the following expression is factorised.

1/4nˆ2 (n+1)ˆ2 – 1/2n(n+1)

= 1/4n(n+1)(nˆ2+n-2)

If anybody could show a working of how that answer is acheived it would be much appreciated.

Thanks!

Use more brackets to make it readable.

3. The attachment shows how it appears in the textbook I am using, hopefully this helps

4. I got $-\frac{1}{8}n^6+1$????
