- 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:
