Answer

True

Work Step by Step

By a form of one, the book means expressions like $\frac{x}{x}$. While this is not the number one, it simplifies to one. Since one times any number is the original number, it is just as valid to multiply the entire expression by $\frac{x}{x}$ as by 1. Thus, forms of one can be useful during the simplification process.
