Question 304616
Like this you mean?
{{{sqrt(x)+2=sqrt(x-1)}}}
Square both sides.
{{{x+4*sqrt(x)+4=x-1}}}
{{{4*sqrt(x)+4=-1}}}
{{{4*sqrt(x)=-5}}}
{{{sqrt(x)=-(5/4)}}}
{{{x=25/16}}}
Check the solution,
{{{sqrt(25/16)+2=sqrt(25/16-1)}}}
{{{2 +- 5/4 = 0 +- sqrt(9/16)}}}
{{{2 +- 5/4 = 0 +- 3/4}}}
The statement is true because
{{{2-5/4=3/4}}}
