n(n+1) + 2(n+1) over 2 = (n+1) (n+2) over 2

 

Can someone explain the steps taken in between?

 

Thanks!

Assuming all of it is over 2 not just the "2(n+1) over 2"

 

(n+1) is common factor. so n(n+1) + 2(n+1) becomes

 

(n+1) (n+2)

 

Then just chuck it all over 2 to get

 

(n+1) (n+2) over 2

As above reply, what you have is

 

xy + xz = x(y+z)

 

 

if it makes looking at it any simpler.

 

 

(with a factor of half out the front)
