Can you factor the denominator?

x=5 or x=2

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 :(

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 \(x^2\)?

I'm a bit confused. Are you stuck with the simplification or the excluded values?

i dont think it is (A) now

It is not C. Look back at the equation. \[\frac{(x2)}{(x+5)(x2)}\]How can you simplify this?

\[\frac{\cancel{(x2)}}{(x+5)\cancel{(x2)}}\]What do you get?
 2 years ago

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