Question 361107
{{{x-sqrt(2x)-8=0}}}
...
add {{{ +sqrt(2x) to  both  sides}}}
...
{{{x-8=sqrt(2x)}}}
square both sides
{{{(x-8)^2=2x}}}
{{{x^2-16x+64=2x}}}
{{{x^2-18x+64=0}}}
...
solve using quadratic formula
discriminant = 68
{{{x1= (18+sqrt(68))/2}}}
x1= 13.123
{{{x2= (18-sqrt(68))/2}}}

x2=4.876
