We know that roots of the quadratic equation ax2 + bx + c = 0 is given by

Now, comparing quadratic equations 4x2 + 4\(\sqrt{3}\)x + 3 = 0 with standard quadratic equation ax2 + bx + c = 0, we get a = 4, b = 4\(\sqrt{3}\) and c = 3.
Therefore, the roots of given quadratic equation are


Hence, the given quadratic equation has two equal roots \(\frac{-\sqrt{3}}{2}.\)
