§ What is the difference between simplifying and expanding?
ú When we simplify the expression, we get rid of the operaon symbol for mulplicaon
and we write the factors next to each other. Somemes we might have to mulply
numbers together before wring it next to the variable(s). Expanding means that we
write the expression as a product of the factors using the “•” symbol for mulplicaon .
§ How would you describe the following terms?
1. Factor: A number or variable that is mulplied to get a product.
2. Variable: A leer used to represent a number.
3. Product: The soluon when two factors are mulplied.
4. Coefficient: The factor that mulplies the variable.
