Extend and apply the distributive law to the expansion of algebraic expressions(ACMNA190)
[/fusion_text][fusion_text]LO:To apply the distributive law to an expression
Know:
- What an expression is
- The four basic operations of numeracy
Understand:
- That the distributive law is used to simplify algebraic expressions..
Do:
- I can apply the distributive law..
What is the distributive law?:
- How can distributive laws be used?
Notes
An expression is a simplified form to represent something.
Sometimes in order to solve equations you need to expand the simplified form out.
When you expand the expression out, it’s called the distributive law.
Eg.)
3 (x + 5) can be written out as 3x + 15.
4p (3q + 9a) = 12pq + 36ap (usually when we re-write expressions, we do it in alphabetical order)[/fusion_text][/fullwidth][fusion_text]
