导言:乘数代数表达式
章节大纲
-
In prior math classes and in Chapter 1 of this book, we factored numbers to find the least common multiple. This helped us to find a common denominator, simplify fractions, and simplify square root expressions. We will use factoring of algebraic expressions in these and many other ways. It is an essential skill that will be required for the remainder of this book and in subsequent math classes.
::在先前的数学课和本书第一章中,我们为找到最不常见的多重而计算数字。 这有助于我们找到一个共同的分母, 简化分数, 简化平方根表达式。 我们将用这些和许多其他方式来计算代数表达式。 这是本书其余部分和随后的数学课需要的基本技能 。By the end of this chapter, you should be able to:
