I want to get-rid of dandelions from a lawn of a couple acres, and I
have been doing some reading.
There is a basic list of things to do, and one of them is to make a
healthy lawn but it is never explained whether this will get rid of
dandelions or does it only prevent them.
My questions is...can you take you dandelion filled lot and do all of
the lawn building activities (aerate, fertilize, over-seed, water,
etc) and end up getting rid of the dandelions, or is that impossible?
Do you have to go to the chemical warfare?

You can pull them. There are some excellent gadgets to help available. A
handheld sprayer with weed-b-gon or equivalent can make it easier with minimum
chemical usage by spraying only the weeds.

Fertilizing and watering will not kill them in my experience, but you will get a
lot less new ones with a healthy lawn.
