'Ausrotten' (to eradicate) is a separable verb. The prefix 'aus-' stands at the end of the sentence in main clauses, but remains attached to the verb in subordinate clauses.
Manche Krankheiten rottet man nur schwer aus.
Some diseases are difficult to eradicate.
The word comes from 'aus' (out) and 'rotten', which is related to 'Wurzel' (root). The literal meaning is therefore 'to tear out by the root' and describes complete destruction.

The gardener had to eradicate the weeds by the roots.
The context makes the meaning clear: if it is about living things such as animals, plants, or diseases, the literal destruction is meant. If it is about abstract things such as prejudices or poverty, the figurative meaning is meant.

'erhalten' and 'ausrotten' are clear opposites here. 'erhalten' means to preserve something and protect it from disappearing.
