Depends on the context. In physics it's speed of light.\[2.9979\frac{m}{s^2}\]
Err. Missing the 10^8
Big difference there ;)
lol yea :D
And that's m/s not m/s^2. I need coffee.

Wrong, speed of a light in a vacuum.
\[4+\sqrt{16 - 4* -1* c} --------------------- =-5 2*-1
Not so much wrong as not completely right :) On to the actual problem.
C=5. Give me a minute to show the work.
alright!

\[\frac{4+\sqrt{16-4(-1)(c)}}{2(-1)}=-5\] Times each side by -2: \[4+\sqrt{16+4c}=10\] \[\sqrt{16+4c}=6\] Square both sides: \[16+4c=36\] \[4c=20\] \[c=5\]
For a moment I thought we'd start up on a discussion about relativity and space-time fabric. :P
