Cubic Equation

A Cubic Equation is defined as the roots of a Cubic Function.

• AKA: Third-Order Polynomial Equation.
• Context:
  • It can be a Univariate or a Multivariate equation.
• Example(s):
  • [math]\displaystyle{ ax^3+bx^2+cx+d=0, \quad a \ne 0 }[/math].
  • [math]\displaystyle{ f(x,y) = a x^3 + by^3 + cx^2+dx^2+ex y+ f x+ gy + h = 0, \quad a \ne 0, \quad b \ne 0 }[/math].
  • …
• Counter-Example(s):
  • a Linear Function.
• See: Cubic Function, Root of a Function, Polynomial.
