1. katlin95 Group Title

@jim_thompson5910 i got 9

2. electrokid Group Title

It cannot be this way! $\sqrt{x+16}-\sqrt{x-2}=0$

3. katlin95 Group Title

so what would be my answer then?

4. electrokid Group Title

is the question the way I wrote?

5. katlin95 Group Title

yep

6. electrokid Group Title

if the question is exactly like I wrote, then there can be no solution for it!

7. katlin95 Group Title

for the second part the sqrt is only over 2x

8. electrokid Group Title

check the question and use the equation editor below to enter the equation

9. katlin95 Group Title

I mean x lol

10. electrokid Group Title

see..!!

11. electrokid Group Title

so, like this?$\sqrt{x+16}-\sqrt{x}-2=0$

12. katlin95 Group Title

yes:)

13. jim_thompson5910 Group Title

if the equation is $\sqrt{x+16}-\sqrt{x}-2=0$, then the answer is x = 9 like you got katlin95, so congrats

14. electrokid Group Title

then yes.
