Explanation:

A split - infinitive occurs when a word or phrase comes between 'to' and the base form of the verb. In "I hope to quickly finish the worksheets so that I can study for the quiz", "quickly" splits the infinitive "to finish". In "The dancers must take time to completely warm up before the performance", "completely" splits the infinitive "to warm up".
