x-2/x^2+3x-10
is this the question? : \[\large{\frac{x-2}{x^2+3x-10}}\] ?

Can you factor the denominator?
what do you mean ??
x=-5 or x=2
Right. So that means \(x^2+3x-10=(x+5)(x-2)\). That means your rational expression becomes\[\frac{(x-2)}{(x+5)(x-2)}\]Before we go farther, can you tell me what the excluded values will be?
i dont know :(
The excluded values are the zeroes of the denominator. So you get \(x=-5,2\). Now I'm sure that you can simplify it.
so x=0
You have excluded values when your denominator is 0. Also, I've got to go now. If you have questions, I'll be back on later tonight, so I can answer your questions then.
so x2
Do you mean \(x^2\)?
no
x=2?
I'm a bit confused. Are you stuck with the simplification or the excluded values?
sorry one secc

i dont think it is (A) now
(C)????
It is not C. Look back at the equation. \[\frac{(x-2)}{(x+5)(x-2)}\]How can you simplify this?
no
\[\frac{\cancel{(x-2)}}{(x+5)\cancel{(x-2)}}\]What do you get?
(B)
no...You should get \[\frac{1}{(x+5)}\]
o lol (D)
