I get 1.Heres a graph.......
Use Newton's method to approximate the indicated root of the equation correct to six decimal places

The root of x^4-2x^3+5x^2-5 = 0 in the interval [1,2]

-
Start with x_0 = 1.0
Find f'(x) = 4x^3 - 6x^2 + 10x
Keep calculating x_n+1 = x_(n) - f(x_n)/f'(x_n) until you get six places.

Not too hard with a calculator. Easier with a spreadsheet.
