1. Find the product. Find the sum. Find the quotient.
Starter – Day November 24
Content Objective: We will be able to simplify, multiply, and divide rational expressions with 80 percent accuracy.
Language Objective: We will be able to explain why is it necessary to exclude values when simplifying rational expressions.
Find the product.
Find the sum.
Find the quotient.
Find the difference.

2. Expression
Numbers, symbols, and operations grouped together to show the value of something. There is no equal sign.
Example: 2x+6

3. Equation
Numbers and symbols on one side of the equal sign that are exactly equal to numbers and symbols on the other side.
Example: 2+2 = 4
Example: 2x+1=7

4. Terms are separated by + or − signs.
Either a single number or a variable or numbers and variables multiplied together.
Terms are separated by + or − signs.

5. Factor
Numbers or variables you can multiply together to get a number or an expression.

6. Rational Number

7. Irrational Number

8. Note: the polynomial in the denominator cannot be 0 (zero).
Rational Expression
An expression that is the ratio of two polynomials. It is “rational" because one is divided by the other, like a ratio.
Note: the polynomial in the denominator cannot be 0 (zero).

9. Remember: You can't divide by 0 (zero).
Excluded Values
A variable’s values that will make the denominator of a fraction equal to 0 (zero).
Remember: You can't divide by 0 (zero).

10. Simplify each expression and state the excluded values.

11. Simplify each expression and state the excluded values.

12. Simplify each expression and state the excluded values.

13. Simplify each expression and state the excluded values.

14. LAB Writing
Explain why is it necessary to exclude values when simplifying rational expressions.
