WebFeb 4, 2016 · Suppose you want to find the root of the polynomial $f (x) = x^2 - a$. By Newton's method, you could start with an initial guess $x_0 = 1$. The next guess is $x_1 = x_0 - f (x_0)/f' (x_0)$, where $f' (x) = 2x$. Therefore, your new guess is $x_1 = x_0 - (x_0^2 - a)/2x_0$ Share Improve this answer Follow answered Apr 24, 2024 at 0:46 Costa Huang WebSquare roots is a specialized form of our common roots calculator.
