The fraction cannot simplify further.

The fraction cannot simplify further.

You may not cancel the $c$ $c$ terms or the $4$ $4$ terms, because there are $+ and -$ $+ and -$ signs. Only factors may be cancelled.

As an example, consider $c = 11$ $c = 11$

The fraction would become:

$\frac{11 + 4}{11 - 4} = \frac{15}{7}$ $(11+4)/(11-4) = 15/7$

This does not simplify.
