where i am..

I think the unit on rational expressions and equations went by really slow. Thats why i had a really hard time understanding this unit.

Muddiest point :
- dividing rational expressions
-word problems dealing with making an eqautions.

OPERATIONS ON RATIONAL EXPRESSIONS

Todays class we continued working on operations on rational expressions. We looked over the questions that Mr.k gave us. We basically worked on the questions from yesterdays class so the steps are the same. For most of our class we worked on this questions:

1)





-Factor into binomials


2)









- multiply the numerator by the reciprocal of the denominator









-cancel out

3)






- take out the left overs


For the last part of the class Mr.K showed us slides on the smart board about:

Restrictions:
I Addition and Subtraction
*restrict the denominators
II Multiplication
*restrict the denominators
III Division
*restrict everything except the numerator
of the first fraction

Homework for today is Ex: 46 DO NOT DO QUESTION 9.

My Muddiest Point!

My muddiest point in pre-cal is:
- word problems with radicals
- converting to radical forms
- writing each radical as a mixed radical

where i am....

Hello, sorry i couldn't post this up yesterday.. i had basketball tryouts, and i came home late..

Polynomials & Factoring

I think polynomials were pretty easy and so was factoring, but i think i could do better.

Analytic Geometry
i think this was the most hardest unit, i need more help on this one.

Trigonometry
This unit was pretty straight forward except when it came to cosine and sine law questions.

Exponents & Radicals
Im starting to get this unit, more and more question would help :)

So.. this is where i stand!!

Today in class Dr.Eviator gave us Exercise 2: Factoring Review (Common, Simple Trinomial) questions 1-20. DO NOT do questions 14 and 18. If you weren't in class today and you forgot your textbook in your locker here are the questions: .

Exercise 2: Factoring Review (Common, Simple Trinomial)

1. a. 12m-2p
b. a - ar³y

2. a. 2a² - 12ab +ac
b. 6x² - 18z^6y - 6ax³z

3. a. 3r² - 15rh
b. 4n³ - 4n²

4. a. 32xy + 4x³y
b.3mn + 6n²m²

5. a. x² - 7x + 12
b. x² - 10x - 24

6. a. x² + 25 + 24
b. x² - 4x - 12

7. a. x² + x - 72
b. c² - 4c - 12

8. a. 4 - 5c + c²
b. x² - x - 6

9. If x = -3 and y = 4, find the valube of

a. 2x + 3y - xy b. x²y + xy²

10. Solve the equation: 3 - 2(x+1) = 5x + 4

11. Solve the equation: x/2 + 1 = x/3

12. Simplify the following expressions:

a. (3x)³
b. (4x²y)(3xy²)
c. 16x²y/ 4xy

13. If AB = 6 and BC = 10, find

a. the length of AC

b. the measure of angle B accurate
to the nearest degree

15. Find the Value of x to two decimal places.

16. Simplify: 3(x + 2) - 2(x + 3)

17. Simplify: (x + 2)(x + 1) - x(x + 3)

19. Simplify: 2[2x - (3 - x)]

20. The side of a square is (x + 4) cm. Find an algebraic expression for its area.

These questions are all due for Monday. Try to do all the questions. And the next scribe is....

LEVINIA!!!
