Hey, I have a couple of questions from my book, I either didn't understand
or couldn't get the right awnser for.. it would be amazing if you could help!!
Thanks soo much.


1.
2s2(squared)+14s-16
________________
2(s2(squared)+7s-8)




2.
ax2(squared)+6ax+9a


3.
t2(squared)-9 = t2(squared)-9
__________ ____________
t +7 t+12 (t+3)(t+4)



4.
x-1 - 3x-2
___ ____
5 10



5.
4 - 2
_______ ________
2m2-m-1 m2+2m -3



thanks again!

Is this question 1?

I think this is question 2

hah yeah I know I had it all perfect with exponents & everything! I was like Gah this will look good .
but then it changed it.. and I was like like .. oh god. what ever haha

yeah, the formatting here can get messed up, it doesn't register spaces, you when you press space over and over to create a gap or something, it doesn't actually do anything. there are tricks to getting the formatting to work seamlessly if you don't use LaTex.

However, i discovered this nice program just yesterday, and now i use it whenever something will be a pain to type out perfectly

yeah what is? please click "quote" when you're replying, so i know which of my messages you are responding to. or tell me, "yeah, you are right about question so and so"

haha alright..

Uh that is question 3..
& I did the work but I came out with a diffrent awnser then my text book so

I foiled the one bottom

thee t(sqred)+7t+12

& I got
t(sqrd) - 9
---------------
(t+3)(t+4)


but.. yeah I dont even know whats up with my text book

Here's question 4

Hold on, let me get this straight. for question 3 you put the question and your answer? You should tell me when you are doing that. did you do that for any others?

--------------------------------------------------------------------------------

for t squared, type t^2, we use the "^" symbol to show that the number immediately following the symbol is a power of the number immediately before the symbol

No.. I just glanced at it before I wrote it down.

I didn't even notice it before I typed it in.
thanks so much for helping me haha I'm kinda a mess :S

Here's number 5

ok, can you just clarify number three now. did i get all the other questions correct?

once i have all the solutions up, look over them, if there is anything you don't get, ask away. you have a test tomorrow, you need to know how to do these yourself

I get how you did it all now.. & I can immediatley see what I did/or didn't do.

for number 4., I believe my teacher told us to multiply the entire equasion buy (in this case 10) .

would that result in the same awnser in the end?



& with number 3.

its

t^2-9
_________
t^2 + 7t + 12
(that looks a little better doesnt it)

yes that does look better, but it looks like you had to do a lot of work to get it so nicely. here's the conventional way to do it without LaTex

(t^2 - 9)/(t^2 + 7t + 12)

now that i have the question, i can post the solution
