Моля да решиш задачи 2 и 6

Let's go through solving each equation requested.

### Problem 2
The equation given is:
\[
x^2 - 7x + \sqrt{x^2 - 7x + 4} = 2
\]

To solve this, follow these steps:

1. **Isolate the square root term**:
   \[
   \sqrt{x^2 - 7x + 4} = 2 - (x^2 - 7x)
   \]

2. **Square both sides** to eliminate the square root:
   \[
   x^2 - 7x + 4 = (2 - (x^2 - 7x))^2
   \]
   (Continue simplifying and solving for \( x \).)

### Problem 6
The equation given is:
\[
\sqrt{x^2 + 4x + 1} + \sqrt{2x^2 + 8x + 9} = 4
\]

To solve this, follow these steps:

1. **Isolate one square root term**, for example:
   \[
   \sqrt{x^2 + 4x + 1} = 4 - \sqrt{2x^2 + 8x + 9}
   \]

2. **Square both sides** to eliminate the square root on the left side:
   \[
   x^2 + 4x + 1 = (4 - \sqrt{2x^2 + 8x + 9})^2
   \]
   (Continue simplifying and solving for \( x \).)
