Question 1172301
.
<pre>

You start with

    {{{x/y}}} - {{{y/x}}} = {{{1/z}}}



Multiply both sides by xy

    x^2 - y^2 = {{{(xy)/z}}}

    y^2 + {{{y*(x/z)}}} - x^2 = 0.



It is a quadratic equation for "y" with coefficients  a= 1,  b= {{{x/z}}},  c = {{{-x^2}}}.



Now apply the quadratic formula to get an expression of  " y "  via coefficients.
