Newton's Iterative method was used to find the root of the equation near 1.5:2x^3-4x^2+3x-6=0.Solution: Newton's Iterative method is also called Newton tangent method. Setf =2x^3-4x^2+3x-6,F1 is the derivative of the equation, thef1 = 6x^2-8x+3, and f1= (f (x0) -

big or it is difficult to see whether it is a multiple of 17, we need to continue the process of "tail truncation, doubling, subtraction, and verification" until we can clearly determine whether it is possible. Another method: if the difference between the last three digits of an integer and the first three digits of an integer can be divisible by 17, then the number can be divisible by 17.
