Witrynar = roots(p) returns the roots of the polynomial represented by p as a column vector. Input p is a vector containing n+1 polynomial coefficients, starting with the coefficient of x n. A coefficient of 0 indicates an intermediate power that is not present in the equation. For example, p = [3 2 -2] represents the polynomial 3 x 2 + 2 x − 2.
WitrynaFinding Roots of Polynomials. Let us take an example of the polynomial p(x) of degree 1 as given below: p(x) = 5x + 1. According to the definition of roots of polynomials, ‘a’ is the root of a polynomial p(x), if P(a) = 0. Thus, in order to determine the roots of polynomial p(x), we have to find the value of x for which p(x) = 0. Now, 5x ...
