In algebra, a quartic function is a function of the form f ( x ) = a x 4 + b x 3 + c x 2 + d x + e , {\displaystyle f(x)=ax^{4}+bx^{3}+cx^{2}+dx+e,} where a is nonzero, which is defined by a polynomial of degree four, called a quartic polynomial. A quartic equation, or equation of the fourth degree, is an equation that equates a quartic polynomial to zero, of the form a x 4 + b x 3 + c x 2 + d x + e = 0 , {\displaystyle ax^{4}+bx^{3}+cx^{2}+dx+e=0,} where a ≠ 0.
