Just for clarity that is 1 over 2 (as in a half, I don't know how to make it look like it does on my page using my computer keyboard).
The answer they gave is:
2A - ah
--------
h
I got...
2A - a
--------
h
I'm confused about how the h ended up on the top and the bottom of the equation when you would be simply multiplying by 1 over h or should you be working out the expression so that is becomes ah + bh first?
