Best practice

Always use the correct past tense form "did not extend" instead of "did not extended". The auxiliary verb 'did' already indicates past tense, so the main verb 'extend' should be in its base form.

Common error

Avoid using "did not extended" as it's a common mistake to incorrectly conjugate the verb after the auxiliary verb "did". Remember that after "did not", the base form of the verb should be used: "did not extend".
