Simply. Helppppppppp pleaseee P² 2p 1
————— - ————— + —————
(y-p)^y. (y-p)^y-1. (y-p)^y-2

(2p(p - y - 1) + y^2)) / (y - p)^y.

Step-by-step explanation:

p^2 / (y - p)^y - 2p / (y - p)^y + 1 / (y - p)^y-2

The LCD is (y - p)^y

NOTE : (y - p)^y /  (y - p)^y-2 = (y - p)^(y - (y - 2)) = (y - p)^2

So we have

(p^2 - 2p + 1( (y - p)^2) / (y - p)^y

= ( p^2 - 2p +y^2 - 2py + p^2) / (y - p)^2

= (2p^2 - 2py - 2p + y^2) / (y - p)^y

= (2p(p - y - 1) + y^2)) / (y - p)^y.

The picture is the answer tell me if you need help!

Hope this helps and have a great day!!
