Question 28293
ln x + ln(x-2) = 1
ln [x(x-2)] = 1
x(x-2) = e
{{{x^2 - 2x - e = 0}}}


{{{ x = (-b +- sqrt(b^2 - 4ac))/(2a)}}}
{{{ x = (2 +- sqrt((-2)^2 - 4(1)(-e)))/(2(1))}}}
{{{ x = (2 +- sqrt(4 + 4e))/2}}}
{{{ x = (2 +- sqrt(4(1 + e)))/2}}}
{{{ x = (2 +- sqrt(4)*sqrt(1 + e))/2}}}
{{{ x = (2 +- 2sqrt(1 + e))/2}}}
{{{ x = 2(1 +- sqrt(1 + e))/2}}}
{{{ x = 1 +- sqrt(1 + e)}}}
