5 / (a+h) - 5 / a
-------------------------- =
h
[5a-5(a+h)] / a(a+h)
----------------------------- =
h
[(5a-5a-5h) / a (a+h)]
-------------------------- =
h
-5h/a(a+h)
-----------------=
h
[-5h] / [ha(a+h)]=
-5/a(a+h)=
-5/[a^2+ah]

-5a^2h - 5ah^2 (^2 meaning squared)
Not sure if it's right, though

first you must make the denominators equal
[ 5/ (a+h) ] * a
and
(-5/a) * (a+h)
= 5a / a(a+h) - 5 (a+h)/ a(a+h)
----------------------------------------
h
this equals
5a- 5(a+h)
--------------
a(a+h)
------------------
h
= 5a-5a+5h
-------------------
a(a+h)
---------------
h
=5h
-----------------
a(a+h)
---------------
h
you then multiply only h by 1/h
and multiply:
5h
-----------------
a(a+h)
by 1/h to get rid of h on the bottom
= 5h
------------
a(a+h)h
= 5
----------
a^2+h
