Work out an approximate solution to x^3+2x-1=0 use the iteration. Help please?

Approximate solutions are the estimate values of an equation

The approximate solution of the equation is x = 0.45

The equation is given as:

The iteration is given as:

To start with, we have:

So, we have:

The next iteration is:

The next iteration is:

The next iteration is:

The next iteration is:

Notice that:

x5 and x6 have the same value to 2 decimal places.

i.e.

Hence, the approximate solution of the equation is x = 0.45
