<p>I thought....hmmm</p>
<p>What did you put for the problem with ax5+bx4+cx3+dx2+ex+f or something? I put 1, but I didn't think then that if a=0, then you could have 0 roots. Was it a kind of 'self-understanding' that a is not 0? I thought so. If not, I screwed up</p>
<p>it was 1 and there is already a thread about that.</p>
