Let's solve the quadratic equation using the method of completing the square.

The equation provided is:
\[
x^2 + 10x + 22 = 0
\]

### Step 1: Move the constant term to the right side
First, subtract 22 from both sides to move the constant term to the right-hand side:
\[
x^2 + 10x = -22
\]

### Step 2: Complete the square
Now, we need to complete the square on the left side. To do this, take half of the coefficient of \(x\) (which is 10), square it, and add it to both sides.

\[
\left(\frac{10}{2}\right)^2 = 25
\]

Add 25 to both sides:
\[
x^2 + 10x + 25 = -22 + 25
\]
\[
(x + 5)^2 = 3
\]

### Step 3: Solve for \(x\)
Now, take the square root of both sides:
\[
x + 5 = \pm \sqrt{3}
\]

Finally, solve for \(x\):
\[
x = -5 \pm \sqrt{3}
\]

Thus, the solutions are:
\[
x = -5 + \sqrt{3}, \quad x = -5 - \sqrt{3}
\]

### Answers for the form and solution boxes:
- **Form**: \((x + 5)^2 = 3\)
- **Solution**: \(x = -5 + \sqrt{3}, -5 - \sqrt{3}\)
