<PRE><B>Question 251423</B>
simplify if possible. 
u+y/uy^2 + 2u+y/u^2y 
----
I am assuming you a listing 4 terms
I am assuming you did not mean (u+y)/uy^2 + (2u+y)/u^2y
---
lcd = u^2y^2
---------------
Rewrite each term with the lcd as its denominator:
---
u^3y^2/lcd + uy/lcd + 2u^3y^2/lcd + y^2/lcd
---
Combine the numerators over the lcd:
= [u^3y^2 + uy + 2u^3y^2 + y^2]/lcd
---
= [u^3y^2 + uy + 2u^3y^2 + y^2]/(u^2y^2)
===========
