WebBrentq Method¶. Brent’s method is a combination of bisection, secant and inverse quadratic interpolation. Like bisection, it is a ‘bracketed’ method (starts with points \((a,b)\) such that \(f(a)f(b)<0\).. Roughly speaking, the method begins by using the secant method to obtain a third point \(c\), then uses inverse quadratic interpolation to generate the next possible root.

WebFinding 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 ...
