To use Newton's method to find all roots of an equation correct to six decimal places, follow these steps:

- Start with an initial guess ( x_0 ) for the root.
- Use the formula ( x_{n+1} = x_n - \frac{f(x_n)}{f'(x_n)} ) to iterate and update the guess until the desired accuracy is achieved.
- Repeat the iteration process until the difference between successive approximations is within the desired tolerance level.

Here's a basic algorithm:

- Choose an initial guess ( x_0 ).
- Calculate ( f(x_0) ) and ( f'(x_0) ).
- Update the guess using the formula ( x_{n+1} = x_n - \frac{f(x_n)}{f'(x_n)} ).
- Repeat steps 2 and 3 until the desired accuracy is achieved.

Repeat this process for each initial guess to find all roots of the equation.

Please provide the specific equation for which you want to find the roots using Newton's method.
