We are given the equation:

\[
x^2 - \frac{1}{x^2} = 12
\]

Let's solve it step by step.

### Step 1: Add 2 to both sides.
We aim to rewrite the equation by recognizing a pattern.

Add \(2\) to both sides:

\[
x^2 - \frac{1}{x^2} + 2 = 12 + 2
\]

This simplifies to:

\[
\left(x - \frac{1}{x}\right)^2 = 14
\]

### Step 2: Solve for \(x - \frac{1}{x}\).
Now, take the square root of both sides:

\[
x - \frac{1}{x} = \pm \sqrt{14}
\]

### Step 3: Let \(y = x - \frac{1}{x}\), and solve for \(x\).
Now we have two equations to consider:
\[
x - \frac{1}{x} = \sqrt{14}
\]
or
\[
x - \frac{1}{x} = -\sqrt{14}
\]

For each case, solve for \(x\) using the quadratic equation or an appropriate method.
