Question 268884
Simplify (4x^2-y^2)/(2x+y)
_____________
8x^3-y^3 
I factored each term 
(2x-y)(2x+y)/(2x+y)
_______________
(2x+y)(2x-y)(2x+y)    ****  = (2x-y)*(4x^2 + 2xy + y^2)
--------------------
--------------------
Cancelled out the like terms. 
I believe my answer is either 
1
_____________
4x^2+2xy+y^2 
-------------- This is correct, tho I don't see how you got it.
= {{{1/(4x^2 + 2xy + y^2)}}}
--------------

Or 
4x^2-2xy+y^2   This is close, not correct.
