For questions related to roots of a cubic equation. All of the roots of the cubic equation can be found by the following means: algebraically, trigonometrically or numerical approximations of the roots.
The solutions of of a cubic equation are called the roots of the cubic function. All of the roots of the cubic equation can be found by the following means:
- algebraically, that is, they can be expressed by a cubic formula involving the four coefficients, the four basic arithmetic operations and $n$th roots (radicals).
- trigonometrically
- numerical approximations of the roots can be found using root-finding algorithms such as Newton's method.
