The expressions “have to” and “have to” are much debated and there is no single position among scholars, a single answer. Some believe that it doesn't matter, others that there is a difference between the constructions.
Let's make some reflections:
The term “that” performs, among others, the function of a relative pronoun, that is, it establishes a relationship between the clauses or with something that was said previously, takes up information said. Example:
My mother has many things what to do. (Who has “to do” something? My mother. The “what” takes up every previous sentence: “My mother has many things to do”.
So, whenever there is a need to go back to a background, use “what” and not “from”.
Therefore, in sentences where there is no need to go back to something, that is, there is no antecedent, use “from”. Examples:
I have to pay my friend.
Students had to take the test in less time.
To make it less complicated, some adopt the approximate meanings of the expressions “I have to” and “I have to”. Look:
have to – expresses an idea of obligation, necessity, duty.
I have to study for the exam tomorrow. (I need to study)
Have to – expresses an idea of “something for”, “things for”.
He has a lot to study. (He has a lot of subjects to study)
Important: To avoid the repetition of “whats” in the essay, analyze what can be replaced by “from” or for (to) which, to (the) which.
