How to find the discriminant of a cubic polynomial?

You can apply the discriminant to any cubic equation, so it doesn’t matter what the original equation looked like. We will use a simple example to show you how to do this. The formula for the discriminant of a cubic polynomial is:

How to find determinant of a cubic polynomial?

So, now let’s consider the discriminant of a cubic polynomial. The discriminant of a polynomial is the square of its radical. This is denoted by The radical of a polynomial is the sum of all its roots. If there are no complex roots, the discriminant is just the sum of the squares of the roots. If there is a repeated root, it does not appear in the sum. There are a few ways to find the discriminant

How to determine the discriminant of a cubic polynomial?

In order to determine the discriminant of a cubic polynomial you need to find the roots of the polynomial. A polynomial has a root if the discriminant is equal to 0, i.e., if the polynomial can be factored into a product of two linear terms. Cubic polynomials have up to three roots, which is why the discriminant of a cubic polynomial is important. If you have a rational cubic root, you can represent

How do you find the derivative of a cubic po

The derivative of a cubic polynomial is a quadratic polynomial. To find the discriminant of a cubic polynomial, find the roots of the derivative. If the roots are complex numbers, then the discriminant is complex. If the roots are real numbers, then the discriminant is the square of the sum of the roots.

How do you find the discriminant of a cubic polynomial?

Aside from the fact that the discriminant is the product of the roots of a cubic polynomial (counting multiplicities), there is no other practical way to find it. Cubic polynomials are notoriously difficult to solve, and the discriminant is no exception. The best way to find the discriminant, especially for a low-degree polynomial, is to use a computer algebra system. There are still ways to work out the discriminant of a cubic polynomial
