Today we reviewed what we have learned in Chapter 9. We went through each section.
For those students who came in late or who have not learned certain parts, either in Chapter 9 or earlier chapters, it is up to you to make up for those parts.
We will have our mid-term exam next week. It will be a close-book test.
The week after the exam, our class will participate in the school wide math contest. More detail will come later.
Today we started the new chapter, CH 10, and covered 10.1, 10.2, 10.3. We talked about polynomial addition, subtraction, and multiplication. We talked a few often used formulae.
For addition and subtraction, it is important to combine only like terms. For multiplication, we talked about FOIL method for multiplying two binomials. For any two polynomial multiplication, just remember to multiply every term in one polynomial to every term in the other polynomial, and add them together.
For the special formulae, the following three are important to memorize:
(a – b)(a + b) = a^2 – b^2
(a + b)^2 = a^2 + 2ab + b^2
(a – b)^2 = a^2 – 2ab + b^2
For the homework:
P580, #47, 49, 51, 53, 55 – 62
P587, #36 – 47
P593, #27 – 42
Let me know if you have any question.
For this coming Sunday, we will do a review of what we have learned for this semester, getting ready for the mid term exam the week after.
