About This Set
These 25 questions check the first step of each method in the chapter: the square and cube identities, the rule, squares that add up to zero, powers of , the remainder theorem and pairs of linear equations. The types are mixed, so you also have to spot which method a question needs. Allow about 25 minutes and answer all of them before reading any explanation. With fewer than 20 right, reread the topic section for each type you missed, then start Practice Set 2.
