Areteem: Math Challenge I-C Handout 9

Online Course Discussion Forum

I'm getting stuck on the following questions. Could someone please help me with these? *-*

Question 9.23:

factors: (x+3)

Question 9.25:

Question 9.28:

2(x^2-1)+(x-2)(x-1)-(x-2)(x+1)

2x^2-2+x^2-3x+2-x^2+x+2

2x^2-2x+2

2x^2-2x+2/(x-2)(x^2-1)=1

(x-2)(x^2-1)/(x-2)(x^2-1)+[2x^2-2x+2/(x-2)(x^2-1)]=0

x^3-3x+4/(x-2)(x^2-1)=0

Thanks so much!

Take a look at the other post on the forum about this handout for some pointers on problems 23 and 25.

For 28 it seems you are making great progress so far! Just double check the second to last line of your work.

Uhhh...

How do I post a topic on the forum?

On the main forum page: https://classes.areteem.org/mod/forum/view.php?id=1827 there should be a green "Add a Discussion Topic" button at the top. That will add a new discussion topic.

See the image below for a screenshot.
