To eliminate a low spot, fill with ready-mix latex under layment. This is premixed so all you need to do is spread it on the floor and smooth it with a floor trowel. Be sure to feather the edges and after it dries, use a carpenters level to make sure the low spot in leveled. If it's still off a little fill with some latex under layment until you get it right.
