Simplify:

(1)  (x+4)^2 
(x+4)^2=(x+4)(x+4)
x+4
x+4
---------
x^2+4x
   +4x+16
-------------
x^2+8x+16




(2)  (x+5y)(x-5y) 
x+5y
x-5y
----------
x^2+5xy
   -5xy-25y^2
------------
x^2-25y^2






(3)  (x^3+7x^2+7x-15)/(x+3) 

   
     x^2+4x-3
    -----------------
x+3/x^3+7x^2+7x-15
    x^3+3x^2
    ------------
       4x^2+7x-15
       4x^2+12x-15
       -----------
           -5x-15
           -5x-15
           -------
             R=0
