Find all complex solutions of 3x^2+3x+4=0.

(if there is more than one solution, separate them with commas.)

Given equation is

Now we can compare it with general form of quadratic equation ()
a = 3 , b = 3 and c = 4

Now we can apply quadratic formula which is given as


Now we can plugin value of a , b or c

        
In general we know
So we can write
So

So or
