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.<\/p>\n
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.<\/p>\n
For the special formulae, the following three are important to memorize:<\/p>\n
(a – b)(a + b) = a^2 – b^2
\n(a + b)^2 = a^2 + 2ab + b^2
\n(a – b)^2 = a^2 – 2ab + b^2<\/p>\n
For the homework:<\/p>\n
P580, #47, 49, 51, 53, 55 – 62
\nP587, #36 – 47
\nP593, #27 – 42<\/p>\n
