uppose a is a simple root of the polynomial f(x) and g(x) is another polynomial of degree > degree of f(x). Then g(x)/f(x) = (A/x-a) + other terms. Prove that A= g(a)/f'(a) by not using L'Habitial's rule.

Let f(x) be a polynomial and let r be a root of f(x). If x_1 is sufficiently close to r then x_2 = i(x_1) is closer, x_3 = i(x_2) is closer still, etc. Here i(x) = x - f(x)/f'(x) is what we called the improvement function a. Let f(x)=x^2-10. Compute i(x) in simplified form (i.e. everything in one big fraction involving x). Let r = sqrt(10) and x_1=3. Show a hand computation of x_2 and then x_3, expressing both your...
