Transcript

  • 1. Factoring Trinomials Module 10 - Topic 2 Part 1
  • 2. Standard Form of a Trinomial Standard form for a trinomial is: ax + bx + c 2
  • 3. Standard Form of a Trinomial Standard form for a trinomial is: ax + bx + c 2 Such as
  • 4. Standard Form of a Trinomial Standard form for a trinomial is: ax + bx + c 2 Such as (A) 3x + 2x + 9 2
  • 5. Standard Form of a Trinomial Standard form for a trinomial is: ax + bx + c 2 Such as (A) 3x + 2x + 9 2 (B) 2t − 5t + 7 2
  • 6. Standard Form of a Trinomial Standard form for a trinomial is: ax + bx + c 2 Such as (A) 3x + 2x + 9 2 (B) 2t − 5t + 7 2 (C) d + 4d − 1 2 Notice the variable doesn’t have to be x.
  • 7. Identifying Parts of a Trinomial ax + bx + c 2 Such as 3x + 2x + 9 2
  • 8. Identifying Parts of a Trinomial ax + bx + c 2 Such as 3x + 2x + 9 2 a=3 b=2 c=9
  • 9. Identifying Parts of a Trinomial ax + bx + c 2 Such as 3x + 2x + 9 2 2t − 5t + 7 2 a=3 b=2 c=9
  • 10. Identifying Parts of a Trinomial ax + bx + c 2 Such as 3x + 2x + 9 2 2t − 5t + 7 2 a=3 a=2 b=2 b = −5 c=9 c=7
  • 11. Identifying Parts of a Trinomial ax + bx + c 2 Such as 3x + 2x + 9 2 2t − 5t + 7 2 d + 4d − 1 2 a=3 a=2 b=2 b = −5 c=9 c=7
  • 12. Identifying Parts of a Trinomial ax + bx + c 2 Such as 3x + 2x + 9 2 2t − 5t + 7 2 d + 4d − 1 2 a=3 a=2 a =1 b=2 b = −5 b=4 c=9 c=7 c = −1
  • 13. Multiplying Binomials Review Recall that multiplying 2 binomials resulted in a trinomial.
  • 14. Multiplying Binomials Review Recall that multiplying 2 binomials resulted in a trinomial. Such as: ( 2x + 3) ( x + 5 ) = 2x 2 + 13x + 15
  • 15. Multiplying Binomials Review Recall that multiplying 2 binomials resulted in a trinomial. Such as: ( 2x + 3) ( x + 5 ) = 2x 2 + 13x + 15 Given the result, the 2 binomial factors are not apparent but sometimes you want to find the binomial factors.
  • 16. Factoring Trinomials when a > 1 Watch a 4 minute video to learn the box method for factoring trinomials. This method can be applied to all factorable trinomials (and some binomials!).
  • 17. More Factoring... In the previous example all terms were positive but this isn’t always the case.
  • 18. More Factoring... In the previous example all terms were positive but this isn’t always the case. Sometimes b, c, or b & c are negative. Such as:
  • 19. More Factoring... In the previous example all terms were positive but this isn’t always the case. Sometimes b, c, or b & c are negative. Such as: 2x + 7x − 15 2
  • 20. More Factoring... In the previous example all terms were positive but this isn’t always the case. Sometimes b, c, or b & c are negative. Such as: 2x + 7x − 15 2 or 12x − 11x + 2 2
  • 21. More Factoring... In the previous example all terms were positive but this isn’t always the case. Sometimes b, c, or b & c are negative. Such as: 2x + 7x − 15 2 or 12x − 11x + 2 2 or 30x − 11x − 14 2
  • 22. More Factoring... In the previous example all terms were positive but this isn’t always the case. Sometimes b, c, or b & c are negative. Such as: 2x + 7x − 15 2 or 12x − 11x + 2 2 or 30x − 11x − 14 2 Watch this 4 minute video to learn how to factor using boxes when b is negative.
  • 23. Gizmo Practice Activity Please log into Explore Learning website using the username and password given to you AND found in the support documents. Search for the "Modeling the Factorization of 2 ax +bx+c" Gizmo and launch the Gizmo. After you have completed at least 5 Gizmo problems, scroll down to the Assessment Questions and complete the 4 multiple choice problems. Pronto or message me if you have questions.
  • 24. Factoring Practice Try these Cool Math problems to practice factoring trinomials when a > 1. Keep working until you get 3 in a row correct without a hint! Select “Give me a Problem” to keep trying problems. After completing your work in a notebook, select “What’s the Answer?” to compare your answer with the correct answer. Message or Pronto me if you need help!
  • 25. Great Job! You’ve finished reviewing Factoring when a > 1. Exit and proceed to Factoring Trinomials Part 2.
