Question

hello
can anyone help? :))

Answer 1

i need to simplify this:
\[(\frac{\sqrt{1+x} }{ \sqrt{1+x}-\sqrt{1-x} }+\frac{ 1-x }{ \sqrt{1-x ^{2}}+x-1 })*(\sqrt{x ^{-2}-1}-\frac{ 1 }{ x })\]

Answer 2

and i got to this point:
\[(\frac{ \sqrt{1+x} }{ \sqrt{1+x} -\sqrt{1-x}}+\frac{ 1-x }{ \sqrt{(1-x)(1+x)}+x-1 })*\frac{ \sqrt{(1-x)(1+x)}-1 }{ x }\]
but i don't know what do do from here..

Answer 3

so , anyone? ://

Answer 4

i don't think it can be simplified. do you know the answer? or if there is an answer?

Answer 5

put 1+x=a,
1-y=b
