the answer is A

Would u mind explaining how u got that? :)

- amistre64

a rational expression is not defined as a polynomial; something to do with the definitions lol

- amistre64

the bottom poly can be factored into what?

- anonymous

-3 and 3 rite?

- anonymous

oh wait -3 and -3

- amistre64

not what are the roots; but what is its factored form?
(x )(x )

- anonymous

ohhhhh (x - 3) (x - 3)

- amistre64

now we can see what makes this turn to 0 and be bad for a denominator....
x = 3 right?

- anonymous

Ahh! ya i see overall what u did :)

- anonymous

Gotcha! ok then thanks :)

- amistre64

youre welcome :)

So then if you simplify the attached file , what would it be?

- amistre64

it wouldnt simplify it would just change from fatored to unfactored forms

- amistre64

(x+4)(x-4)
---------
(x-3)(x-3)

- anonymous

Right but then what would that simplify to? >.< sorry im confused there is no option for that answer :)

- amistre64

in order to simplify and equation; you have to be able to reduce it down by cross out like factors top and bottom; there are none in this case

- amistre64

2x 1
--- simplifies ---
4xy 2y

- anonymous

Thats strange here are the options for simplifying it gives me i will attach them in files :)

- amistre64

this one....doesnt simplify; its as basic as you can get it

- amistre64

1 and 4 are negative of each other so they simply go to -1

- anonymous

Yes and so i assumed it would be the file labeled three would that be rite? :)

- amistre64

3 doesnt simplyfy so much as just factors out
1
------
3(2x-3)

- amistre64

number 2 simplifies; maybe lol

- amistre64

-9 3
------ = -----
-6x+9 (2x-3)

- anonymous

Ohhh!!! ok! ok! :D thankies!! :) lol

- amistre64

youre welcome :)
