Did not get.. Excluded value??

2. dietrich_harmon

that 's how the problem don't know what else u asking for

3. waterineyes

I also don't know what you are asking for... Ha ha ha...

4. dietrich_harmon

okay i guess

5. waterineyes

Hey, I got it..

6. waterineyes

Is this your question : $\frac{2x + 6}{4x – 8}$

7. dietrich_harmon

yes

8. waterineyes

I just want to know that is their any divide sign or / sign between 2x + 6 and 4x – 8??

9. waterineyes

*there.

10. waterineyes

So, excluded value is the value which can make the denominator 0.. As, you know denominator must not be 0, that is why this value is to be excluded and is called Excluded Value..

11. waterineyes

So, you have to just put your Denominator = 0: And then find x from it: $4x - 8 = 0$ Find x here..

12. benfraser1012

set the denominator = 0, so 4x - 8 = 0 so 4x = 8. Now find the value of x. and this x value will be the excluded value as you cant use the x you find for this equation.

13. waterineyes

Can you find the value of x here ???

14. waterineyes

15. benfraser1012

yup!!!

16. dietrich_harmon

yup

17. benfraser1012

you can do this @dietrich_harmon.

18. waterineyes
