<PRE><B>Question 943180</B>
 x- sqrt(2*x-1)=2 add sqrt(2x-1) to each side
x-sqrt(2x-1)+sqrt(2x-1)=2+sqrt(2x-1) subtract 2 from each side
x-2=sqrt(2x-1) square each side
(x-2)^2=2x-1
{{{x^2-4x+4=2x-1}}} add 1 to each side
{{{x^2-4x+5=2x}}} subtract 2x from each side
{{{x^2-6x+5=0}}}
*[invoke quadratic &quot;x&quot;, 1, -6, 5 ]
ANSWERS are x=5 and x=1
