# How is this so?

I'm not seeing how you get 1/4k = (1/2)k(1/2)k(1/2)

I understand why you can factor out the (1/2). It's in each term of the sum.

I haven't really looked at this crap in four years.

That's not what they have. Although you can factor out the 1/2 because of the "+1" in the denominator of the expression.

Yeah, I got the +1 part. I feel silly for not immediately following their steps.

(22)k?
