**Solving cubic or higher degree polynomials by hand**

20/10/2005Â Â· Hello, I'm using Excel 2000. Is there any function that will help me solve for the roots of a cubic equation? Alternatively, does anyone have a macro â€¦... Here find the two roots of the equation according to the principle described in the previous section. They are the numbers: 3 and -2. So, a concrete cubic equation has three roots: 2, -2 and 3.

The problem is that you can't always find a factor easily, where as the formula always works. I mean, how would you solve I mean, how would you solve x^2 + 23x + 7 = 0 by using just the factor theorem and not the formula/completing the square/some other method which isn't the factor theorem?...

## How To Find Roots Of Cubic Equation Easily

### 30/01/2000Â Â· It's very funny the way this one works. You have to choose a square root AND a cube root, so the expression takes on six possible values. But a cubic equation has only three roots.

- 24/02/2010Â Â· The last of these is easy to solve since all we have to do in that case is find the cube root of -d/a to solve the equation. Similarly, if the constant term is missing, one of the roots is x = 0. We can then reduce the equation to a quadratic by removing the common factor from all three terms, and solve it using either the factorization method or the quadratic formula.
- â˜… CUBIC RESOLUTION â˜… To make the cubic equation easier , we can eliminate the constant terms from the leading coefficients and variable respectively , which will result in the expression :
- Quadratic equations. Shortcut Tricks are very important things in competitive exam. Time is the main factor in competitive exams. If you know how to manage time then you will surely do great in your exam.
- There are various way to find out the roots or zeros of the cubic functions i.e. algebraically, trigonometrically and also in the form of complex number. Cubic functions are generally derived by the help of quadratic equation or function. There is a process for finding the zeros of derivatives of a cubic function by the help of quadratic formula:
