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. WebA quadratic equation in its standard form is represented as: ax 2 + bx + c = 0, where a, b and c are real numbers such that a ≠ 0 and x is a variable. The number of roots of a polynomial equation is equal to its degree. So, a …
