In italian there are special names for particular kind of (polinomial) equations of degree two, namely given a polinomial equation
ax2+bx+c=0 whe call it (I use the italian names)
pura, when b=0 and so it becomes ax2+c=0 (pura=pure,neat,mere)
spuria, when c=0 and so it becomes ax2+bx=0 (spuria=spurious)
We was wondering where those names come from, and the answer could maybe found also considering the existence of similar (o different) terminology in other languages.
Se il drago rifiuta di combattere,
forse è solo pigro.
Ma se ignora la zanzara,
allora è davvero addormentato.
