Point to note: For a quadratic equation complex roots  are conjugate of each other 
Equation x2+2x+4=0  have complex roots say z1 and z2 and z2 = conjugate(z1)
suppose Z1 is root of ax2 +bx +c=0 then the other root is conjugate(z1) = z2.
This means both equations are essentially same.
Hence a:b:c = 1:2:4

I must correct that in this case both equations are not exactly same but the ratio of coeficients for both equation will be same which will give the same answer.
a:1 = b:2 = c:4
