Solution :

◍ There won't be any real solution for x if b² < 4ac

So, have to less than 4×3×k = 12k

 \:  \:  \:  \:  \:  \:  \:  \:   \dashrightarrow \:  \: \sf {k}^{2}  - 12k   &lt; 0 \\  \\

 \:  \:  \:  \:  \:  \:  \:  \:  \dashrightarrow\sf \:  \:  k(k - 12) &lt; 0 \\  \\

 \:  \:  \:  \:  \:  \:  \:  \:  \dashrightarrow  \:    \sf \: k \in(0,12) \\  \\

k have to (0,12) for the solution being imaginary.
