Witryna4 lip 2014 · Let's say the equation is x 3 + 3 x 2 + 3 x + 1 = 0 :D. One root is found to be -1. Then divide the original expression by x + 1 to get x 2 + 2 x + 1 = 0. By observation, you can see that x=-1 is a triple root, but the program can't so, as a general rule, we have to divide the original expression by the factor. – tpb261 Jul 4, 2014 at 11:55 Witryna16 lis 2024 · Let’s work an example of Newton’s Method.
