help algebra.. simplifying

OpenStudy (anonymous):

wait..

OpenStudy (anonymous):

y = 4 square root of 4-x/x / 1+ 4-x/x

OpenStudy (anonymous):

LOL can you rewrite the expression it is confusing

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

okay\[y = \frac{4\sqrt{\frac{ 4-x }{ x }} }{ 1+ \frac{ 4-x }{ x } }\]

OpenStudy (anonymous):

\[ \frac{ 4-x }{ \frac{x}{1+\frac{4-x}{x}}}\]

OpenStudy (anonymous):

k let us assume 4-x/x as t and substitute in the equation

OpenStudy (anonymous):

y =4sqrt(t)/(1+t)

OpenStudy (anonymous):

okay okay..

OpenStudy (anonymous):

but what to do next?

OpenStudy (anonymous):

you have to solve the equation?

OpenStudy (anonymous):

need to derive the answer x^2 + y^2 - 4x

OpenStudy (anonymous):

ohh that is easy no need to do the t thing

OpenStudy (anonymous):

just solve the denominator first

OpenStudy (anonymous):

so in the denominator we will have (x+4-x)/x after solving our complete expression will be
