Found this in the internet, hope it helps:

Find the Solution for

3x2+2x+3=0

using the Quadratic Formula where

a = 3, b = 2, and c = 3

x=−b±b2−4ac−−−−−−−√2a

x=−2±22−4(3)(3)−−−−−−−−−−√2(3)

x=−2±4−36−−−−−√6

x=−2±−32−−−−√6

The discriminant b2−4ac<0

so, there are two complex roots.

Simplify the Radical:

x=−2±42–√i6

x=−26±42–√i6

Simplify fractions and/or signs:

x=−13±22–√i3

which becomes

x=−0.333333+0.942809i

x=−0.333333−0.942809i
