Hello!

I would really appreciate some help, I need to simplify these;


x + √x
------- (I know that this one is √x, but how does it get to that?)
1 + √x


and;


x
------- + √(1-x)
√(1-x)



and;



1 - x
-------
1 + √x



Thank you!

factor out from the numerator:

we get:

now continue

and;


x
------- + √(1-x)
√(1-x)

begin by combining the fractions. then what would you get?

and;
1 - x
-------
1 + √x
Thank you!

think of as

now expand that using the difference of two squares. what do you get?

Thank you - for not really telling me the answers but instead giving me just enough hints to work it out for myself. ;D

Thanks again.
