is this the question? : \[\large{\frac{x2}{x^2+3x10}}\] ?

Can you factor the denominator?

what do you mean ??

x=5 or x=2

KingGeorge Group TitleBest ResponseYou've already chosen the best response.1
Right. So that means \(x^2+3x10=(x+5)(x2)\). That means your rational expression becomes\[\frac{(x2)}{(x+5)(x2)}\]Before we go farther, can you tell me what the excluded values will be?

i dont know :(

KingGeorge Group TitleBest ResponseYou've already chosen the best response.1
The excluded values are the zeroes of the denominator. So you get \(x=5,2\). Now I'm sure that you can simplify it.

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.

Do you mean \(x^2\)?

KingGeorge Group TitleBest ResponseYou've already chosen the best response.1
I'm a bit confused. Are you stuck with the simplification or the excluded values?

(C)????

KingGeorge Group TitleBest ResponseYou've already chosen the best response.1
It is not C. Look back at the equation. \[\frac{(x2)}{(x+5)(x2)}\]How can you simplify this?

KingGeorge Group TitleBest ResponseYou've already chosen the best response.1
\[\frac{\cancel{(x2)}}{(x+5)\cancel{(x2)}}\]What do you get?
 one year ago

KingGeorge Group TitleBest ResponseYou've already chosen the best response.1
no...You should get \[\frac{1}{(x+5)}\]
