Separate the fraction!:)

Hi! Could somebody can me, please?

I want to separate this expression ([G + 1/T]*Omega^2) / ([4*Delta^2] + [G + 1/T]^2) into two parts so that one would be (G * Omega^2) / (4*[Delta^2 + G^2/4])

or

separate this expression Omega^2/(4*[Delta^2 + G^2/4]) into two parts so that one would be (G * Omega^2) / (4*[Delta^2 + G^2/4])!

Thanks a lot!:)

You have a fraction "A" and want to "separate" it (write as a sum?) so that one part is B. Well, then the other part is A- B isn't it?
