1+(√a-1)^2/√a-1
--------------------------
√a-1-√a+1
----------------------
a^2-1
=2+a+2√a/√a-1
---------------------------=0 part 1 completed
0/a^2-1
part 2of 98 question
=√a-1
--------------------
a-1√a+1-a+1√a-1
=using rf
=√a-1(a-1√a+1+a+1√a-1)
-----------------------------------------
(a-1√a+1)^2-(a+1√a-1)^2
=a^2-1+(a+1)a^2+1-2√a
--------------------------------------
(a-1√a+1)^2-(a+1√a-1)^2
=a^3+a-2a+1-2√a+1+a^2+√a-1
------------------------------------------------
a^2+a+1-a√a-√a+1-a^2-a-1-a√a+√a+a
=a^3+a-2a+1-2√a+1+a^2+√a-1
---------------------------------------------
-2a√a
