Hello can somebody help me to solve this question using scilab or matlab? ( both are almost the same).

The question is solved in this page but in theory:

https://www.chegg.com/homework-help/fourth-degree-polynomial-f-x-230x4-18x3-9x2-221x-9-two-real-chapter-2.3-problem-13e-solution-9781305253667-exc

Here i give the programs of each

Method to make it easier:

*newton:

*secant:

*fake rule:

*example:

How can i use this methods to approximate the zeros of f ?????

The fourth-degree polynomial f(x) = 230x4 + 18x3 + 9x2-221x-9 has two real zeros, one in [-1, 0] and the other in [o, 1]. Attempt to approximate these zeros to within 10-6 using the a. Method of False Position b. Secant method c. Newton's method The fourth-degree polynomial f(x) = 230x4 + 18x3 + 9x2-221x-9 has two real zeros, one in [-1, 0] and the other in [o, 1].
