I have no problem expanding brackets with fractions generally, unless the fraction contains an unknown variable, such as in the following expression:(adsbygoogle = window.adsbygoogle || []).push({});

m/4[6m - 8] + m/2[10m - 2]

I know that the answer is:

12/2m^{2}- 3m

..but I have no idea how to get to that. Can anyone help?
