The cubic equation formula is used to represent the cubic equation. A polynomial having degree three is known as a cubic polynomial or we can call it a cubic equation. Cubic equations have at least one real root and they can have up to 3 real roots. The roots of a cubic equation can be imaginary as well but at least 1 must be real. The cubic equation formula along with a few solved examples is explained below. Let us explore them.
What Is Cubic Equation Formula?The cubic equation formula can also be used to derive the curve of a cubic equation. Representing a cubic equation using a cubic equation formula is very helpful in finding the roots of the cubic equation. A polynomial of degree n[1] will have n number of zeros or roots. The cubic equation is of the following form:
ax3+bx2+cx+d=0
We can solve the cubic equation by two methods
i) Trial - Error and Synthetic Division ii) Factorization.
