l presume you mean imaginary numbers?

 

3x^2 + 3 =0

 

3x^2 = -3

 

x^2 = -1

 

Since you sqaure root a negative 1 to get x....

 

x = i

3x^2 + 3  = 0      divide through by 3

 

x^2 + 1  = 0        subtract 1 from both sides

 

x^2  =  -1            take the pos/neg roots

 

x  = ±√-1

 

x  =  i      or x = - i

 

 

cool cool cool
