The quadratic formula
\(x = -4 \pm 3√(3)\) simplifies to
\(x = -4 + 3√(3)\) and
\(x = -4 - 3√(3)\).

The given quadratic formula is:


\[ x = (-b \pm √(b^2 - 4ac))/(2a) \]

In this case, the quadratic equation seems to be in the form
\(ax^2 + bx + c = 0\), and the quadratic formula gives solutions for x.

The quadratic formula you provided is:


\[ x = -4 \pm (6√(3))/(2) \]

Now, let's simplify the expression:


\[ x = -4 \pm 3√(3) \]

So, the correct answer is:

a.
\( x = -4 \pm 3√(3) \)
