: 52) a+4 a+4
------=-----
2 a
I can't remember how to figure this one out and the examples from the book aren't making it any easier for me. I am not sure if i am suppose to find a common denominator which i would think would be 2a and then times each one by the one that would make the denominator 2a.
thank you so much

a+4 a+4
------=-----
2 a
-----------------------------
least common denominator = 2a
------------------------
Rewrite each fraction with the lcd as its denominator:
---
[a(a+4)/lcd] - [2(a+4)/lcd]
---
Combine the numerators over the lcd:
-----
[a^2+4a -2a - 8]/lcd
---
[a^2 + 2a - 8]/[2a]
