Use Newton’s method with the specified initial approximation x1 to find x3, the third approximation to the root of the given equation.

x^5 ? x ? 4 = 0

x1 = 2
.

Administrator answers:

With f(x) = x^5-x-4, Then f ‘ (x) = 5x^4 -1

X2= x1- f(x1)/f ‘(x1)

x2= 2- f(2)/f ‘(2)

= 2- 26/79

= 1.67088…

X3= x2- f(x2)/f ‘(x2)

Depending on how many decimal places…

X3= 1.6709- f(1.6709)/f ‘(1.6709)

= 1.4773

I hope this helps!
