You're going to need to use your parenthesis differently.  You might have a problem with the grouping if you leave it as it is.  It'd be better written as this:

print (-b + /sqrt ((b*b) - (4*a*c))/(2*a))

I don't know the function for square root either, but I'm sure one of the others will answer that for you.
