Witryna3. A possible algorithm to find all roots of the polynomial P consists in: Start from some X0 and find a root R, using Newton's algorithm. Divide P by (X-R): the division is exact (up to numerical error) since R is a root. (this step is called deflation) Restart from the beginning if the quotient has degree > 1. Witryna18 gru 2013 · Dec 18, 2013 at 14:05. @user2906011 That means if you have an equation, say x^2 = 4, then to solve it one would have to pass a function returning x^2-4 because the Newton-Raphson solver finds x such that the function gives 0. If x^2-4=0, then x^2=4, so a solution to the function is a solution to the equation. – Ramchandra …
