If the circles
\[
x^2+y^2+2gx+6y+4=0
\]
and
\[
x^2+y^2-gx-2y-14=0
\]
cut each other orthogonally for a positive integral value of \(g\), then the radical axis of the two circles is:
Show Hint
The radical axis of two circles is obtained immediately by subtracting their equations. First determine any unknown parameters, then subtract.
