1. 1. Section P6 Rational Expressions
2. 2. Rational Expressions
3. 3. A rational expression is the quotient of two polynomials. The set of real numbers for which an algebraic expression is defined is the domain of the expression. Because division by zero is undefined, we must exclude numbers from a rational expression’s domain that make the denominator zero. See examples below.
4. 4. Example What numbers must be excluded from the domain?
5. 5. Simplifying Rational Expressions
6. 7. Example Simplify and indicate what values are excluded from the domain:
7. 8. Example Simplify and indicate what values are excluded from the domain:
8. 9. Multiplying Rational Expressions
9. 11. Example Multiply and Simplify:
10. 12. Dividing Rational Expressions
11. 13. We find the quotient of two rational expressions by inverting the divisor and multiplying.
12. 14. Example Divide and Simplify:
13. 15. Adding and Subtracting Rational Expressions with the Same Denominator
14. 16. Add or subtract rational expressions with the same denominator by (1) Adding or subtracting the numerators, (2) Placing this result over the common denominator, and (3) Simplifying, if possible.
