Expand the polynomial - Error on Test 5 - Bigger degree after submission

Hi there,

I’m stuck on this puzzle:

All my unit tests are ok but when I submit, the test 5 is KO.
I think it’s coming from parsing, but as we can’t see the post submission tests I can’t guess the source of the problem. So it’s impossible for me to fix it.

Any suggestion on extra edge-test input will be greatly appreciated!
