%28-2a%5E0%29%2F%28%282a%5E-4%29a%29+=+%28-2a%5E0%29%2F%28%282a%29%2Fa%5E4%29
...
%28-2%281%29%29%2F%282a%2Fa%5E4%29+=+%28-2%29%28%28a%5E4%29%2F2a%29+=+-2a%5E4%2F2a+=+-a%5E3

Alternatively,
%28-2a%5E0%29%2F%28%282a%5E-4%29a%29+=+%28-2a%5E0%29%2F%282a%5E%28-4%2B1%29%29
%28-2%281%29%29%2F2a%5E-3+=+-1%2Fa%5E-3+=+-1%2F%281%2Fa%5E3%29+=+-1%28a%5E3%2F1%29+=+-a%5E3
