The answer to your question is that there is no point in "brute forcing" through a text book in this manner, unless you're cramming for an examination.

Do not read textbooks in this way, especially if you do not own them. If you borrow a textbook through the library, and then read it cover to cover, and not remember anything, that is a waste of time.

Good textbooks are worth owning, which implies that they will be in your possession for years. You can use them for reference, and study them over the years in piecemeal fashion as your wandering interest returns to the topics from time to time.

If you really want to absorb the material in your textbook, you must do the chapter exercises. You can give yourself a course by going through the book, or you can spread this over years.

Maybe the book is a real tour de force on the subject matter and requires a lot of commitment, such that if you put in the commitment, you become an authority on those problem-solving methods. Is that something you want for yourself, though?

The important thing to memorize from your textbooks is just enough of a summary of the ideas that when you encounter some idea in the world, you can remember which of your textbooks has something to say about that topic.

For instance, this book, let's call it Foobley and Bings, has 35 problem-solving methods. Can you remember enough about the gist of the methods so that when you see a problem, you can think "Aha! This problem has a general pattern which fits one of the problem-solving methods in Foobley and Bings." Even if you don't remember the details of the problem-solving method, this can be a big time saver, and the fact that you recognize the pattern shows that you have knowledge. (Even Foobley and Bings themselves may have to crack open their own book to solve that same problem, if they haven't touched the material in years. Maybe the wrote the book to "unload" it from their brains to "make room" for something else, while having something to refer to.)
