Polynomial/Factoring- I don't mind polynomials as much but I dislike factoring..alot
I don't understand how to do factoring questions and SOMETIMES certain question on polynomials.
Analytic Geometry- I understand all the formulas, its just sometime the question is put in a certain way,makes me not understand it AT ALL!..I understand most of it, well, most of the simple questions to point it simply.
Trignometry- I understand cos, sin, tan signs. I know how to find all the sides of the triangles...I know how to do Sine Law and Cos Law.
AGAIN, the way the question is put messes me up..
Radicals and Exponents-..I'm getting a little confused how to do some of the questions but I'm slowly understanding it..

Starting All Over
Today, Mr.K returned to our math class from his long absence and has told us, we are starting all over with the blog.
First, he asked the class how we were doing these past two months and if we needed help on anything. He is willing to help each of us on any of the past few units and only if needed. He expects us to keep track on our current unit, while getting help on past units and work. Also, he is very determined that 100% of us will pass our next quiz.....
The past units are:
- Polynomials/Factoring
- Analytic Geometry
- Trignometry
He also gave us a practice quiz for us to do, which is about radicals. He said it should be a review to us, so he only gave us 5 or 10 minutes to work on it. The practice quiz only consisted of 5 questions. He only looked over 4 of the questions with the whole class, and showed us the correct answers. He taught the class how to figuring out the questions as well.
The practice quiz consisted of questions that helps...
1. How to convert squareroot number to exponential form
example- √10 = 10 1/2 <- exponential form
2. How to convert exponential form to radical form
example- 5 1/2 = √5 <- radical form
3. How to evaluate exponential form
example- 6 -1/2= (1/6)1/2 = 1/3
4. How to write radical as a mixed radical
example- √12 = √4.3 = √4 . √3 = 2√3 <- mixed radical
5. How to write mix radical as an entire radical
example- 5√3 = √25 . √3 = √25.3 = √75 <- entire radical
Vocabulary(For the people who don't understand the words.)
Square Root- A number multiplied by itself.
Exponential Form- A radical form that consists of exponents.
Sorry if this wasn't any help, but I tried :)
Next scribe is my awesome friend, Rowena.

Corrections/Riviewing Grade 9 Math, Multiplying Polynomials.
Today, we now have a different teacher for math class and her name is Mrs.Ingram. For the classmates who doesn't know, the reason why Mr.K is not showing up for class is because he is busy with his personal life outside of school and won't be coming back for awhile.
Today, we looked over our worksheet from last week homework, "Polynomials Exercise 1" and did corrections on it.
I will give you guys the correct answers for the questions below for the worksheet.
1.) Simplify each of the expressions below.
a) (a - 3b) + (2 + 2b)
answer:a+2-b
b) (8k + 3m) + (2k - 5m)
answer:10k-2m
c) (3a + 2b) - (a + 3b)
answer:2a-b
d) 3(2x^2y - 3xy + 7) + (xy - 3x^2y - 2)
answer:3x^2y-8xy+19
e) x(4x^2 + 5x) -2x^2(5x^2 - 2x)
answer:-10x^4+8x^3+5x^2
f) (1/2x + 1/3y) - (3/2x + 2/3y + 5) + (7/2x + 1/5y + 4)
answer:Confusing...ask teacher about this one
2. Find the sum of 7x^4y^3 - 3xy and 6x^5 - 5xy .
answer:6x^5+7x^4y^3-8xy
3. Wanda's age is (4x + 3y + 6) and her daughter's age is (2x - y - 4). Find the difference of their ages , expressing your answer in terms of x and y .
answer:2x+4y+10
Mrs.Ingram gived us examples "Multiplying Polynomials"
example- 3(x^2+6x+9)= 3x^2+18x+27
example- x(x^2+6x+9)= x^3+6x^2+9
example- (x+4)(x-2)= x^2-2x+4x-8= x^2+2x-8
Today homework is in our textbook.
"Multiplying Polynomials" Riviewing.
Exercise 1 questions#1-10
MUST BE DONE BY TOMORROW!
IF YOU EVER NEED HELP IN ANYTHING IN MATH!!
**REMEMBER TO ASK PEOPLE FOR HELP, DON'T BE SHY, YOU CAN ASK ME FOR HELP FOR EXAMPLE** & BE POSITIVE!! X)
Next Scribe is..........KRIS!?
