The problem asks to solve the equation 

\[
600x^4 - 550x^3 + 200x^2 - 20x - 1 = 0
\]

using two numerical methods:

1. **Bisection method** 
2. **Newton's method** 

The solution should be accurate to within \(10^{-4}\), and the interval for the solution is given as \(0.1 \leq x \leq 1\).

### a. Bisection Method
The Bisection Method is an iterative method that finds roots by repeatedly bisecting an interval and selecting subintervals where the function changes sign. To apply it:

1. Find \(f(a)\) and \(f(b)\) for the endpoints \(a = 0.1\) and \(b = 1\). If \(f(a)f(b) < 0\), there is a root in the interval.
2. Calculate the midpoint \(c = \frac{a + b}{2}\).
3. Check the sign of \(f(c)\). If \(f(a)f(c) < 0\), the root lies between \(a\) and \(c\); otherwise, it lies between \(c\) and \(b\).
4. Repeat the process until the absolute error \(|b - a|\) is less than the desired accuracy \(10^{-4}\).

### b. Newton's Method
Newton's Method is an iterative method that approximates roots using tangents. To apply it:

1. Start with an initial guess \(x_0\) within the interval \(0.1 \leq x \leq 1\) (usually, you take the midpoint of the interval as the initial guess).
2. The iteration formula is:
   \[
   x_{n+1} = x_n - \frac{f(x_n)}{f'(x_n)}
   \]
   where \(f'(x)\) is the derivative of \(f(x)\).
3. Repeat the process until the absolute difference between consecutive approximations \(|x_{n+1} - x_n|\) is less than \(10^{-4}\).

### Steps to solve
- For the Bisection Method: Calculate \(f(0.1)\) and \(f(1)\), then follow the steps outlined.
- For Newton's Method: Find the derivative of the function \(f(x)\), choose an initial guess, and iterate.

Here are 5 related questions to expand understanding:
1. How do you determine if the Bisection method is applicable for a given interval?
2. What is the derivative of the given function for use in Newton’s Method?
3. How do initial guesses affect the convergence speed of Newton's Method?
4. Can the Bisection Method ever fail to find a root in an interval?
5. What are some advantages of using Newton's Method over the Bisection Method?

**Tip:** Newton’s method can converge quickly but may fail if the initial guess is far from the root or if the derivative near the root is zero.

Use the Bisection Method and Newton's Method to solve the equation 600x^4 - 550x^3 + 200x^2 - 20x - 1 = 0 for the interval 0.1 ≤ x ≤ 1, with a solution accurate to within 10^-4.
