Our generated misspelling index lists 13 likely wrong-spelling variants for quadratic, with forms such as "qaudratic", "qquadratic", and "quadartic".

Our confusable-pair dataset has no match for it, since nothing in our dataset looks or sounds close enough to cause mix-ups.

Etymologically, the entry records: From French quadratique (1765), from Latin quadrātus + -ique (English -ic), form of quadrō (“I make square”), from quādrus (“square”), ultimately from Proto-Indo-European *kʷetwóres (“four”), whence also Latin quartus (“fourth”).
