How to concurrently, efficiently remove repeated instances of the same text in a PDF? 1

[scherz0]

This purchased PDF (that I didn't create) repeats the text, underlined in green, under each diagram. Undeniably, deleting each instance one by one is too inefficient! How can I delete this text productively, synchronously, at one fell swoop?

Since you paid for this file, why don't you ask for a version of it without this text?

I'm surprised Pearson is offering PDF without any security. They're pretty militant about copyright.
