  • 1. Intro Video
  • 2. UNIT 8-6
    Solving Rational Equations and Simplifying Expressions
  • 3. Section 1!!!
    Here, you will learn how to solve rational equations!!!
  • 4. How To Solve
    To start, you first need to find the Least Common Denominator (or LCD)!
    LCD= (28)(Z+2)
  • 5. How To Solve
    You then multiply by the LCD, to get rid of the denominator.
  • 6. How To Solve
    Now, you just simplify the equation and solve for X.
  • 7. How To Check
    First, you plug in the amount you got for the variable, and simplify.
  • 8. How To Check
    Then, you combine like terms, and make the 2 fractions on the right side have a common denominator, so they can be combined.
  • 9. How To Check
    Finally, you combine like terms again… and simplify. If both sides are equal to each other, then your answer is correct, if not, you may want to go back and check your work.
  • 10.
  • 11. Practice #1
    In the equation (1/n+2)+(1/n-2)=(3/n2-4), what is N?
  • 12. Practice #1
    In the equation (1/n+2)+(1/n-2)=(3/n2-4), what is N?
  • 13. Practice #1
    In the equation (1/n+2)+(1/n-2)=(3/n2-4), what is N?
  • 14. Did You know It?
    The correct answer was… N=3/2! Your work should have looked something like this.
  • 15. Practice #2
    In the equation…
    What is W?
  • 16. Practice #2
    In the equation…
    What is W?
  • 17. Practice #2
    In the equation…
    What is W?
  • 18. Did You Know It?
    The correct answer was…W=-2! Your work should have looked like this.
