UP:MA19.8A.5
Vocabulary
- like terms
- Expression
- Factor
- properties of operations (Appendix D, Table 1)
- Difference of squares
Knowledge
Students know:
- Properties of operations (including those in Appendix D, Table 1),
- When one form of an algebraic expression is more useful than an equivalent form of that same expression.
Skills
Students are able to:
- -Use algebraic properties to produce equivalent forms of the same expression by recognizing underlying mathematical structures.
For example, 3(x-5) = 3x-15 and 2a+12 = 2(a+6) or3a-a+10+2and x2-2x-15 = (x-5) (x+3).
Understanding
Students understand that:
- Generating simpler, but equivalent, algebraic expressions facilitates the investigation of more complex algebraic expressions.
