I think I have been here before, just can not remember a way out.

I have a simple example of my problem

restart;
with(geometry);
_EnvHorizontalName:=x;
_EnvVerticalName:=y;
point(P1,[1,1]); ## point on the directrix
point(V1,[2,2]); ## vertex
point(P2,[3,3]); ## focus
## since the vertex is at V1, and the line of symmetry passes through
## the vertex,
line(L,[P1,V1]); ## line os symmetry
detail(L);
PerpendicularLine(Lp,P1,L); ## directrix
detail(Lp);
distance(P2,V1);
parabola(P,['vertex'=V1,'focus'=P2]);
detail(P);
## the equation has sqrt(2) in every term
eq:=Equation(directrix(P)); ## get the equation of the directrix
expand(eq*sqrt(2));    ## This is what I want

How do I get Maple 15 to remove the common sqrt()?
