Cubic equations are equations in the following form. The highest power of x in cubic equations is 3, meaning that the coefficient a of x cube cannot be zero. If a is zero then the equation is not a cubic equation. Below are roots of cubic equations. Roots of cubic equations are useful in solving cubic equations and factoring cubic equations. We will deal with how to solve cubic equations and step by step cubic equations in another section. For this section, we introduce cubic equations and the roots of cubic equation formulas.

Cubic equations can be written in the above form.

Roots of cubic equations

When solving cubic equations, if the roots of the cubic equation are given by:

Then the following Math Formulas are true for the cube roots of the cubic equation.
