Hi, I'm almost at the end of a question but i seem to be stuck. I have the answer though.. so im up to here so can someone please help me arrange this

$\displaystyle (\frac{n + \frac{1}{c}}{\frac{s}{n} }) [\mu^2 - 2\mu(\frac{n \overline{y}}{n+\frac{1}{c}})] $

and make it equal to

$\displaystyle \frac{n + \frac{1}{c}}{\frac{s}{n} + \frac{\overline{y}(\frac{1}{c})}{(n + \frac{1}{c})}}[\mu - (\frac{n\overline{y}}{n + \frac{1}{c}})]^2 $

or if you don't want to give me the full thing, the next line would really help guide me coz i just have no idea what to do

thank you, coz ive tried everything i could think of and nothing seems to work.. Please?
