Question 193587
1/y + 1/(y+2) 
divided by 
1/y - 1/(y+2) 

--------------------------
Simplify the numerator:
= (y+2 + y)/(y(y+2)) = (2y+2)/(y(y+2))
---------------------------------------------
Simplify the denominator:
= (y+2-y)/(y(y+2))
= 2/(y(y+2))
--------------------------
Invert the denominator and multiply to get:
[(2y+2)/(y(y+2))/ * [y(y+2))/2]
---
Cancel the y(y+2) which is common to numerator and denominator:
---
= (2y+2)/2
---
Cancel the common factor of "2" to get:
= 1/(y+1)
