Question: Simplification of a small expression

Is it too much to expect Maple 13 to do some basic simplification that a 8th grader student could do to clean up some of the wacky expressions it outputs?  In the above, why could it not divide by "C" straight away?  And why does it leave a minus sign hanging outside the expression?  A little more development programming effort devoted to output formatting instead of calculating esoterica would be appreciated.
