    you have not made a mistake.

    now you need to factorise out mu2/2 and simplify the two fractions in the bracket.

    Alright, so you can express 1/2 mu^2 as mu^2 /2. Next subtract the 2 fractions as you normally would (hint get the same denominator). Once you have done this the 2 m^2u^2 cancel leaving ya with the required format hope this helps! feel free to msg me if you need further assistance

    simplify 1 - m/{ M + m } in the usual way
