+  // it's a quadratic; the x² term gives it away, and we know the general form is
+  // ax² + bx + c = 0.
+  //
+  // So, let's identify the coefficients: a = 1, b = 4, and c = 4. Now, what's the

+  // often the fastest route if it works. If that fails, I'll default to the quadratic
+  // formula, which is foolproof. Completing the square? It's good for deriving the
+  // formula or when factoring is difficult, but not usually my first choice for
+  // direct solving, but it can't hurt to keep it as an option.
+  //
+  // Factoring, then. I need to find two numbers that multiply to 'c' (4) and add
+  // up to 'b' (4). Let's see... 1 and 4 don't work (add up to 5). 2 and 2? Bingo!
+  // They multiply to 4 and add up to 4. This means I can rewrite the equation as
+  // (x + 2)(x + 2) = 0, or more concisely, (x + 2)² = 0. Solving for x is now
+  // trivial: x + 2 = 0, thus x = -2.
+  //
+  // Okay, just to be absolutely certain, I'll run the quadratic formula just to
+  // double-check. x = [-b ± √(b² - 4ac)] / 2a. Plugging in the values, x = [-4 ±
+  // √(4² - 4 * 1 * 4)] / (2 * 1). That simplifies to x = [-4 ± √0] / 2. So, x =
+  // -2 again – a repeated root. Nice.
+  //
+  // Now, let's check via completing the square. Starting from the same equation,
+  // (x² + 4x) = -4. Take half of the b-value (4/2 = 2), square it (2² = 4), and
+  // add it to both sides, so x² + 4x + 4 = -4 + 4. Which simplifies into (x + 2)²
+  // = 0. The square root on both sides gives us x + 2 = 0, therefore x = -2, as
+  //  expected.
+  //
+  // Always, *always* confirm! Let's substitute x = -2 back into the original
+  // equation: (-2)² + 4(-2) + 4 = 0. That's 4 - 8 + 4 = 0. It checks out.

+//     We can solve this equation by factoring, using the quadratic formula,
+//     or by recognizing it as a perfect square trinomial.
+//
+//     **Method 1: Factoring**
+//
+//     1.  We need two numbers that multiply to the constant term (4)
+//         and add up to the coefficient of the x term (4).
+//     2.  The numbers 2 and 2 satisfy these conditions: 2 * 2 = 4 and 2 + 2 = 4.
+//     3.  So, we can factor the quadratic as:
+//             (x + 2)(x + 2) = 0
+//             or
+//             (x + 2)² = 0
+//     4.  For the product to be zero, the factor must be zero:
+//             x + 2 = 0
+//     5.  Solve for x:
+//             x = -2
+//
+//     **Method 2: Quadratic Formula**
+//
+//     The quadratic formula for an equation ax² + bx + c = 0 is:
+//         x = [-b ± sqrt(b² - 4ac)] / (2a)
+//
+//     1.  In our equation x² + 4x + 4 = 0, we have a = 1, b = 4, and c = 4.
+//     2.  Substitute these values into the formula:
+//             x = [-4 ± sqrt(4² - 4 * 1 * 4)] / (2 * 1)
+//             x = [-4 ± sqrt(16 - 16)] / 2
+//             x = [-4 ± sqrt(0)] / 2
+//             x = [-4 ± 0] / 2
+//             x = -4 / 2
+//             x = -2
+//
+//     **Method 3: Perfect Square Trinomial**
+//
+//     1.  Notice that the expression x² + 4x + 4 fits the pattern of a perfect square trinomial:
+//         a² + 2ab + b², where a = x and b = 2.
+//     2.  We can rewrite the equation as:
+//             (x + 2)² = 0
+//     3.  Take the square root of both sides:
+//             x + 2 = 0
+//     4.  Solve for x:
+//             x = -2
+//
+//     All methods lead to the same solution.
+//
+//     **Answer:**
+//     The solution to the equation x² + 4x + 4 = 0 is x = -2.
