Cubic polynomial
= Cubic polynomial
{title2=$a_3x^3+a_2x^2+a_1x+a_0,\quad a_3\ne0$}
A <cubic polynomial> in one <variable> has <polynomial degree> three. Over a <splitting field>, its <factorization of polynomials> contains three <polynomial factors> of <polynomial degree> one when <multiplicity of a root> is counted.
