WebThe Cardano's formula (named after Girolamo Cardano 1501-1576), which is similar to the perfect-square method to quadratic equations, is a standard way to find a real root of a cubic equation like ax^3+bx^2+cx+d=0. ax3 +bx2 +cx+ d = 0. We can then find the other two roots (real or complex) by polynomial division and the quadratic formula. WebFind an approximation to x with newton’s method to solve x^2 for 3 iterations, starting from x_0 = 1 with 4 significant figures. So, how many decimal places is the estimate solution accurate? Solution: First apply the power rule: Where, x^2 = 2x So, Iteration 1: F (x_0) = f (5) = (5)^2 = 25 F’ (x_0) = f’ (5) = 2 (5) = 10
