I pulled one out of the ground and it had a three inch root that looked like a red carrot. Should I eat it?? and is that the plant establishing itself in the ground to come back next year.???

You don't eat the root. That must remain in the ground so the plant can reproduce each year. In fact, most of the plant is quite poisonous. The only edible portion will be the shoot between the root and leaves. Take care not to eat from any other part of the plant.
