Sorry I don't know the term, but I take math in french.
What we use would translate into "3rd degree equation"
it's

x^3+2x^2+5x+6=0

It's a "level above" quadratic equations correct? So how would I solve this??


extra: My math teacher says x^3 cuts the axis 3 times, that can't be true right??? it'd have to be x^2+x^3-.01???
