    To complete the square for the equation \( x^2 + 12x - 14 = 0 \), we can follow these steps:
1. **Isolate the quadratic and linear terms**:
\[
x^2 + 12x = 14
\]
2. **Complete the square**:
To complete the square, we need to add and subtract \(\left(\frac{12}{2}\right)^2\) (which is \( 36 \)) to the left side of the equation.
Therefore, we will add \( 36 \) to both sides:
\[
x^2 + 12x + 36 = 14 + 36
\]
3. **Rewrite the left side as a square**:
The left side can now be written as a perfect square:
\[
(x + 6)^2 = 50
\]
4. **Take the square root of both sides**:
\[
x + 6 = \pm \sqrt{50}
\]
Since \(\sqrt{50} = 5\sqrt{2}\), we can express it more simply:
\[
x + 6 = \pm 5\sqrt{2}
\]
5. **Solve for \(x\)**:
Subtract \(6\) from both sides:
\[
x = -6 \pm 5\sqrt{2}
\]
So, the complete solution to the original equation is:
\[
x = -6 + 5\sqrt{2} \quad \text{or} \quad x = -6 - 5\sqrt{2}
\]
As we described the steps, the correct entries for what's missing would be:
- In the completing the square step (i.e., the blanks): "36" for both blanks.
- The square root result before solving would have necessitated \( \sqrt{50} \), which simplifies to \( 5\sqrt{2} \).
