## anonymous one year ago Can someone help me with this? x -2 x^2+3x -10

1. anonymous

what do you want to do with it?

2. anonymous

Simplify the rational expressions. State any excluded values. Show your work.

3. anonymous

that's a polynomial expression. A rational expression is a fraction

4. anonymous

Okay.

5. anonymous

Other then that, that's all i have for information

6. anonymous

is that the exact way it's written? there's no numerator/denominator?

7. anonymous

2x/x^2+3x-10 sorry didn't include the division.

8. anonymous

like this? $\frac{ 2x }{ x^2+3x-10 }$

9. anonymous

Yes like that

10. anonymous

Usually you'd factor like this and something will cancel from the numerator and denominator. $\frac{ 2x }{ (x+5)(x-2) }$ Since nothing canceled, the original is already simplified. For excluded values set the denominator equal to 0. $(x + 5)(x - 2) = 0$ So you need to solve $$x+5=0$$ and $$x-2=0$$

11. anonymous

Alright. x+5-5=0-5 x= -5 X-2+2=0+2 = 2

12. anonymous

yes, so -5 and 2 are the excluded values

13. anonymous

Okay.

14. anonymous

So i'm finish @peachpi?

15. anonymous

yeah, unless they asked for something else

16. anonymous

Alright thanks :) bye.
