For extra practice with some of the topics we're learning this year, you can try some DeltaMath problems. These are totally optional and only for extra practice. The code to sign up for this DeltaMath is 368168. It'll be under Mr. Portales's name.
We're starting a new unit on polynomials. First, we'll look at what a polynomial is, then we'll look at quadratics as a special kind of polynomial, and then look at things we can do with all polynomials in general, such as division.
Here is a summary sheet of useful information about quadratics and about polynomials that we will be learning this unit.
Friday, 10/7 - we defined polynomials, saw some of their properties, and looked at an optional skill called "synthetic substitution". Here are the slides from class. Your HW is Ex. 3.1 (old & new edition p. 98) #1, 6, 9, 11.
Tuesday, 10/11 - we looked at the different forms of quadratic functions and parabola graphs. Here are the slides from class. Your HW is Ex. 3.2 (new edition: p. 110; old edition p. 108) #2, 3, 20, 32.
Thursday, 10/12 - we reviewed the discriminant of a quadratic and applied our knowledge about discriminants to a variety of IB problems. Here are the slides from class. Your HW is Ex. 3.2 (new edition: p. 110; old edition p. 108) #21, 22, 27, 29, 33.
Friday, 10/14 - we reviewed your unit 1 exams. Here are the slides from class. Here is the process for completing test corrections. Here is a blank copy of your exam. Your HW is to complete these test corrections, due Tuesday.
Monday, 10/17 - we looked at a useful pattern involving the sum and product of the roots of a quadratic function. Here are the slides from class. Your HW is unfortunately not in your old edition textbook - it is Ex. 3.2 (NE p. 110) #39, 40ace, 43, 44. Here is a worksheet with notes missing from your textbook as well as these HW problems.
Tuesday, 10/18 - we looked at polynomial division. Here are the slides from class. Your HW is (NE p. 124, OE p. 119) Ex. 3.3 #1, 4-6, 9, 11.
Wednesday, 10/19 - you took the PSATs.
Thursday, 10/20 - we looked at the remainder theorem of polynomials. Here are the slides from class. Your HW is (NE p. 124, OE p. 119) (Ex. 3.3) #2, 3, 10, 13, 28, 29.
Friday, 10/21 - we looked at the factor theorem of polynomials. Here are the slides from class. Your HW is (NE p. 124, OE p. 119) (Ex. 3.3) #19, 20, 30, 33, 36.
Monday, 10/24 - we looked at the Fundamental Theorem of Algebra. Here are the slides from class. Your HW is (NE p. 124, OE p. 119) (Ex. 3.3) #21, 23, 24, 26, 27.
Tuesday, 10/25 - we looked at patterns involving the sum and product of roots of general polynomials, not just quadratics. Here are the slides from class. Your HW is unfortunately not in your old edition textbook - it is (NE p. 124) (Ex. 3.3) #37-39. Here is a worksheet with notes missing from your textbook as well as these HW problems.
Wednesday, 10/26 - we did practice problems in our groups to prepare for our exam. Here are the slides from class. Your HW (due Monday) is Chapter 3 Practice Questions (old edition p. 139 and new edition p. 149) # 1, 3, 4, 5, 9, 11-14, 17-19, 21 and Ex. 3.3 (new edition p. 125) #41. Because it is a longer assignment with more difficult problems that you have many days as well as class time to complete, I will count this as an 8 point process category grade.
Thursday, 10/27 - we worked on your HW (due Monday) in class to prepare for our exam. Once again your HW (due Monday) is Chapter 3 Practice Questions (old edition p. 139 and new edition p. 149) # 1, 3, 4, 5, 9, 11-14, 17-19, 21 and Ex. 3.3 (new edition p. 125) #41.
Friday, 10/28 - we have our exam on quadratics and polynomials. Your HW (due Monday) is Chapter 3 Practice Questions (old edition p. 139 and new edition p. 149) # 1, 3, 4, 5, 9, 11-14, 17-19, 21 and Ex. 3.3 (new edition p. 125) #41. Here are the topics for the exam:
