Trying to simplify: (Square root x-2) + 5 divided by (square root x-2) all over x-2. Can anyone help? Thanks!

I hate these.
OpenStudy (anonymous):
sqrt(x-2)+5 / sqrt(x-2)(x-2)....yes?
OpenStudy (anonymous):
Multiplying top and bottom by sqrt(x-2) looks like a good bet...
OpenStudy (anonymous):
No, ((\sqrt{x-2})+ 5/\sqrt{x-2}) / x-2\]
OpenStudy (anonymous):
That's the same...

1/2 divided by 2 is 1/4...
OpenStudy (anonymous):
\[\sqrt{x-2}+5 \over \sqrt{x-2}(x-2)\]
OpenStudy (anonymous):
sorry its backwards but thats what im trying to solve
OpenStudy (anonymous):
Are they all 2's in the picture?
OpenStudy (anonymous):
except for the 5 on the very top

Well, that's straightforward, just add 'em
6 sqrt(x-2) /5(x-2)
OpenStudy (anonymous):
U see?
OpenStudy (anonymous):
maybe? - working on where you got the 6
OpenStudy (anonymous):
Just add at the top, LCD is 5 so u have 5 +1 sqrt(x-2)'s
OpenStudy (anonymous):
and the 5 goes to the bottom along with (x-29

I see. Thanks.
OpenStudy (anonymous):
x-2, sorry

Wait a minute I am reading it upside down....
OpenStudy (anonymous):
It actually says sqrt(x-2) + 5/sqrt(x-2) is that right?
OpenStudy (anonymous):
yes

Ah Ok, moment..
OpenStudy (anonymous):
OK; LCD is sqrt(x-2) so adding
(x+3) / (x-2) sqrt(x-2) is what u want to simplify....
OpenStudy (anonymous):
So multiply top and bottom by sqrt(x-2) to get
sqrt(x-2) (x+3) / (x-2)^2 is your answer.
OpenStudy (anonymous):
Where does the (x+3) come from?
OpenStudy (anonymous):
Your LCD is sqrt(x-2) so when you add you get
sqrt(x-2)sqrt(x-2) +5 = x-2 +5 = x+3

i finally see
OpenStudy (anonymous):
:-) Got there in the end (try to use the equation editor, makes life easier with the odd ones).
OpenStudy (anonymous):
ok thanks
OpenStudy (anonymous):
estudier's solution boils down to\[\frac{x+3}{(x-2)^{3/2}} \]if the numerator and the denominator are divided by\[\sqrt{(x-2) } \]
