Here is the Polynomial

amistre64 · Answer

thats not a polynomial :)

anonymous · Answer

:P Thats strangeee thats the exact question >.< lol

amistre64 · Answer

the answer is A

anonymous · Answer

Would u mind explaining how u got that? :)

amistre64 · Answer

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

amistre64 · Answer

the bottom poly can be factored into what?

anonymous · Answer

-3 and 3 rite?

anonymous · Answer

oh wait -3 and -3

amistre64 · Answer

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

anonymous · Answer

ohhhhh (x - 3) (x - 3)

amistre64 · Answer

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

anonymous · Answer

Ahh! ya i see overall what u did :)

anonymous · Answer

Gotcha! ok then thanks :)

amistre64 · Answer

youre welcome :)

anonymous · Answer

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

amistre64 · Answer

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

amistre64 · Answer

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

anonymous · Answer

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

amistre64 · Answer

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 · Answer

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

anonymous · Answer

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

amistre64 · Answer

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

anonymous · Answer

Here :)

amistre64 · Answer

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

anonymous · Answer

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

amistre64 · Answer

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

amistre64 · Answer

number 2 simplifies; maybe lol

amistre64 · Answer

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

anonymous · Answer

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