Modeling Equivalent Expressions

Equivalent Expressions

Chapter 6 Lesson 7

Simplify each Expression

• To simplify the expression you have to distribute if necessary and then combine like terms

•  $5\left(6x+1\right)$  

•  $\left(5\cdot6x\right)+\left(5\cdot1\right)$  

•  $30x+5$  

Factoring Each Expression

• Remember this is the opposite of the distributive property

• Find the GCF and factor it out of each term.

•  $35x+25y$  

•  $\left(5\cdot7x\right)+\left(5\cdot5y\right)$  

•  $5\left(7x+5y\right)$
