Choose a suitable starting value $\displaystyle \displaystyle \begin{align*} x_0 \end{align*}$, then $\displaystyle \displaystyle \begin{align*} x_{n + 1} = x_n - \frac{f(x_n)}{f'(x_n)} \end{align*}$
For no.1 Expression is negative when x=-1 and positive when x=0 so choose a starting value between -1 and 0
