Answer:    x = −2 ± i

Step-by-step explanation:  solution of ax²+bx+c=0 is given by

                 x= ( -b±√(b²-4ac))/2a

            here a=3,b=12 and c=15

          ⇒    x=  (-12±√(12²-4×3×15))/6

           ⇒   x=  (-12±√(144-180))/6

           ⇒   x=  (-12±√(-36))/6

          ⇒    x=  (-12±6i)/6

            ⇒  x=  -2±i
