What equations have to be equated to get the formula for escape velocity (which i know)

I know the formula for escape velocity but not what formulas that derive it/can be equated to find it.

because orbital velocity is the same except there is no '2'

for an object to achieve escape, it must have enough kinetic energy to get out of the planet's potential well...so to find escape velocity, equate the kinetic energy of the object to the potential energy of the planet

1/2 m v^2 = GMm/r => vesc = Sqrt[2GM/r]

(for orbital velocity, equate forces: force of grav with centrip force

mv^2/r = GMm/r^2 or vorb=Sqrt[GM/r] )
