How do I get Maple to reduce/simplify the following difference quotient to its lowest terms? Basically I need Maple to rationalize the numerator. Any suggestions on how to do this?

f := proc (x) options operator, arrow; sqrt(2*x+1) end proc

proc (x) options operator, arrow; sqrt(2*x+1) end proc

 (1)

expand((f(x+h)-f(x))/h)

(2*x+2*h+1)^(1/2)/h-(2*x+1)^(1/2)/h

 (2)

simplify((f(x+h)-f(x))/h)

((2*x+2*h+1)^(1/2)-(2*x+1)^(1/2))/h

 (3)

rationalize((f(x+h)-f(x))/h)

((2*x+2*h+1)^(1/2)-(2*x+1)^(1/2))/h
