Find the exact solution for
\[\sqrt{5}-1/x =\sqrt{5}/2\]
Then find the approximate solution to the nearest tenth.

i see it, but i cant see your work :D
OpenStudy (anonymous):
sorry but i dont know where to start to try to solve it
OpenStudy (anonymous):
ok, i'll show you
OpenStudy (anonymous):
\[\sqrt{5} - 1/x = \sqrt{5}/2\]
subtract \[\sqrt{5}\]
\[-1/x = \sqrt{5}/2 - \sqrt {5}\]
times x
\[-1 = (\sqrt{5}/2 - \sqrt {5})* x\]
divide by \[ (\sqrt{5}/2 - \sqrt {5})\]
\[\frac{ -1 }{ (\sqrt{5}/2 - \sqrt {5}) } = x\]
\[x=\frac{ 2 \sqrt{5} }{ \sqrt{5} }\]
x= 0.9

is the question
\[\frac{ \sqrt{5} -1 }{ x } or \sqrt{5}-\frac{ 1 }{ x }\]
OpenStudy (anonymous):
the first one you put right there

you always make me do double the work
answer is \[\frac{ -2 \sqrt{5} }{ 5 } + 2 ; 1.1\]
OpenStudy (anonymous):
sorry :(
OpenStudy (anonymous):
