To solve the equation:

\[
4x^6 - 2 = (x^3 + 1)^2 - 2x^3
\]

we’ll simplify and solve for \( x \).

### Step 1: Expand \( (x^3 + 1)^2 \)

\[
(x^3 + 1)^2 = x^6 + 2x^3 + 1
\]

So, substituting this into the equation, we have:

\[
4x^6 - 2 = x^6 + 2x^3 + 1 - 2x^3
\]

### Step 2: Simplify the Right Side

Notice that \( +2x^3 \) and \( -2x^3 \) cancel each other out, leaving:

\[
4x^6 - 2 = x^6 + 1
\]

### Step 3: Rearrange Terms

Now, bring all terms involving \( x \) to one side:

\[
4x^6 - x^6 = 1 + 2
\]

\[
3x^6 = 3
\]

### Step 4: Divide by 3

\[
x^6 = 1
\]

### Step 5: Solve for \( x \)

To solve for \( x \), take the sixth root of both sides:

\[
x = \pm 1
\]

### Final Answer

The solutions to the equation are:

\[
x = 1 \quad \text{and} \quad x = -1
\]
