Given quadratic equation,
x2 + 3 = 0
On comparing it with ax2 + bx + c = 0, we have
a = 1, b = 0, and c = 3
So, the discriminant of the given equation will be
D = b2 – 4ac = 02 – 4 × 1 × 3 = –12
Hence, the required solutions are:
\( \dfrac{-b\pm\sqrt{D}}{2a}\)
= \( \dfrac{\pm\sqrt{-12}}{2\times 1}\)
= \( \dfrac{\pm\sqrt{12i}}{2}\)
= \( \dfrac{\pm2\sqrt{3i}}{2}\)
= \(\pm\sqrt{3i}\)
