Complex plane locus question (another one)

In summary, the equation a + bt + ct^2 = z, where t is a real parameter, can be split into real and imaginary parts to find the locus of z in the complex plane. The locus is a straight vertical line with x = Re(a) when b/c is a pure imaginary number. This may not always be the case, as shown in the example where b = 1 + i and c = 2 + 2i.

Homework Statement



again there is no answer provided in the book!

a +bt +ct^2 = z where t is a real parameter, and a, b, c are complex numbers with b/c real


Homework Equations



The Attempt at a Solution



b/c real indicates that b and c are pure imaginary so when you split the equation into real and imaginary parts:

x = Re(a)

y = Im(a) + Im(b)t + Im(c)t^2

since t is a parameter, in the complex plane, the locus of z is a straight vertical line with x = Re(a)?

Are you sure? What if b = 1 + i and c = 2 + 2i ?
