Andrew,
You can use ImplicitPlot. You must use an "==" sign and not "=" and there
will only be real solutions for certain values of c. Also you will have to
experiment with the x domain, and with some types of equations you will also
need to specify a y domain. Check out the Help for ImplicitPlot in the
StandardPackages.
Needs["Graphics`ImplicitPlot`"]
ImplicitPlot[-5 == (x - x^2) + (y - y^2), {x, -10, 10}]
