### Solving Quadratic Equations by Completing the Square

The problem to solve using the method of completing the square is:

\[ x^2 - 10x - 4 = 0 \]

#### Steps to Solve:

1. **Move the constant term to the other side:**

   Start with the equation:
   \[ x^2 - 10x = 4 \]

2. **Complete the square:**

   Take half of the coefficient of \(x\), square it, and add it to both sides. The coefficient of \(x\) is \(-10\). Half of that is \(-5\), and squaring it gives \(25\).

   Add and subtract \(25\) inside the equation:
   \[ x^2 - 10x + 25 = 4 + 25 \]

   This simplifies to:
   \[ (x - 5)^2 = 29 \]

3. **Solve for \(x\):**

   Take the square root of both sides:
   \[ x - 5 = \pm \sqrt{29} \]

   Solve for \(x\):
   \[ x = 5 \pm \sqrt{29} \]

Therefore, the solutions are:
\[ x = 5 + \sqrt{29} \quad \text{and} \quad x = 5 - \sqrt{29} \]

By following these steps, you can solve the quadratic equation by completing the square.
