Best ResponseYou've already chosen the best response.0is this the question? : \[\large{\frac{x2}{x^2+3x10}}\] ?

Best ResponseYou've already chosen the best response.1Can you factor the denominator?

Best ResponseYou've already chosen the best response.1Right. 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?

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

Best ResponseYou've already chosen the best response.1You 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.

Best ResponseYou've already chosen the best response.1Do you mean \(x^2\)?

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

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

KingGeorge

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

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