simplify complex fraction( x/(x+2))/(1/x)+(1/x+2)

OpenStudy (anonymous):

Which one is the in the numerator?

OpenStudy (anonymous):

Is it x/(x+2)?

OpenStudy (anonymous):

num is x/x+2

OpenStudy (anonymous):

This is how you do it

OpenStudy (anonymous):

X/x+2 is the numerator it stays the same

OpenStudy (anonymous):

Then we move to the denominator

OpenStudy (anonymous):

It becomes (x+2) + x all of it divided by x(x+2)

OpenStudy (anonymous):

The numerator stays the same till now

OpenStudy (anonymous):

The denom becomes 2x+2/x^2+2x

OpenStudy (anonymous):

Are you with me?

OpenStudy (anonymous):

what is the first step that you do with den?

OpenStudy (anonymous):

You find the common factor which is x(x+2)

OpenStudy (anonymous):

I see that dem becomes x(x+2) but what do you do with that?

OpenStudy (anonymous):

Well lets start with the first fraction in the denom

OpenStudy (anonymous):

Then you'll have to divide the common factor which is x(x+2) by x and the answer is (x+2) then you multiply it by 1 which stays the same

OpenStudy (anonymous):

You do the same thing with the second fraction

OpenStudy (anonymous):

Are you getting it?

OpenStudy (anonymous):

looking at it

OpenStudy (anonymous):

then divide x(x+2) by (x+2)=x times 1=X?

OpenStudy (anonymous):

1/2 + 1/4 = ? Do you know how to do it? If you do it's exactly the same way to solve the other question

OpenStudy (anonymous):

2/4+1/4

OpenStudy (anonymous):

x/x+2 +x/x+2?

OpenStudy (anonymous):

So you'll get 3/4

OpenStudy (anonymous):

What is your LCM ?

OpenStudy (anonymous):

x+2

OpenStudy (anonymous):

It is x(x+2)

OpenStudy (anonymous):

Because your multiplying both

OpenStudy (anonymous):

In the first example if you multiplied 2 with 4 you would get 8

OpenStudy (anonymous):

And you'll still get the same answer 3/4

OpenStudy (anonymous):

ok got it thanks

OpenStudy (anonymous):

Did you really get it?

OpenStudy (anonymous):

The final answer should be x^2/2x+2
