1. eli123

2. jim_thompson5910

it looks great, nice work

3. eli123

well i checked it and it says its wrong :/

4. eli123

i'm checking it again

5. jim_thompson5910

hmm does it place any restriction on x and h?

6. eli123

no i only have to simplify it

7. jim_thompson5910

alright one second

8. eli123

rationalize the denominator

9. jim_thompson5910

well what you have is correct, but perhaps the computer system is really picky and they want it a certain way?

10. eli123

probably

11. eli123

if i get it wrong, i could do another one but i really dont want to go through the process again

12. jim_thompson5910

Maybe they want the answer as $\Large \frac{2x+h+2\sqrt{x(x+h)}}{h}$ or maybe as $\Large \frac{2x+h+2\sqrt{x}\sqrt{x+h}}{h}$ or maybe as $\Large \frac{x+h+2\sqrt{x}\sqrt{x+h}+x}{h}$

13. jim_thompson5910

They're all equivalent to what you wrote

14. eli123

yes i got it! i tried the second one

15. eli123

thank you so much!

16. jim_thompson5910

hmm interesting...

17. jim_thompson5910

stupid computer lol, oh well, yw

18. eli123

they really wanted it simplified ! haha

19. jim_thompson5910

yeah it's more simplified the way you had it...idk
