Use Newton's method to approximate the root of the equation
that belongs to the interval (6,12 ).
Start with x0=12 and perform three iterations, i.e., find x1,x2, and x3.
Calculate |x0−x1|,|x1−x2|, and |x3−x2|.
1. Use Newton's method
where the function f has a positive leading coefficient so that f(x)= ???
