Question: How can I stop maple expanding an expression ?

Question:How can I stop maple expanding an expression ?

If I extract the denominator of the following expression

 

> s:=(1/2/Pi+Q*(1-u^2)/(1+u^2))^2/((1+beta^2*(1/2/Pi+Q*(1-u^2)/(1+u^2))^2)*(1+u^2));

maple expands it automatically

s2:=denom(s);

but the result of solving the expanded denominator

solve(s2=0,u);

 

is different to the result of solving the non-expanded expression

s1:=((1+beta^2*(1/2/Pi+Q*(1-u^2)/(1+u^2))^2)*(1+u^2));

 

solve(s1=0,u);

 

and so I would ideally like to prevent the expansion of the expression. I have tried frontend and indets commands but to no avail; is there a function you could suggest that would prevent the expansion?
