How do you use this equation?
mgh+1/2mvh=mgh+1/2mv^2+Fd

How you use it depends upon the problem you are trying to solve.
It looks like you are trying to use conservation of energy to solve a problem of height and velocity of an object moving in a gravitational field, with a work or drag term (Fd) included. However the mvh on the left would have to be mv^2. Even more important, the v's and h's on the right and left sides shoule have different subscripts, since they would apply to different times along the trajectory.
