If I remember elementary calculus, the limit is -c/a
The internal Limit gives DirectedInfinity[-a + Sqrt[a^2]) (formatting
excised)
After <<Calculus`Limit` I get
On::"none": "Message \!\(Power :: \"infy\"\) not found."
On::"none": "Message \!\(Power :: \"indet\"\) not found."
On::"none": "Message \!\(\\[Infinity] :: \"indet\"\) not found."
General::"stop":
"Further output of \!\(On :: \"none\"\) will be suppressed during
this \
calculation."
For Limit[Sqrt[(25 + 2 x 3] - 5)/x, x -> 0] they both give 3/5 so at
least THAT works.
HELP! Please. How do I get this to work so I can address more general
cases where the solution isn't so obvious?

You shouldn't either.
