FP2 complex numbers: Adding and subtracting them (Argand diagrams)

So the mark scheme doesn't ever account for the line being through the origin, it always wants you to have it in the other position to form a vector triangle.

They are the exact same thing if we are to consider them as vectors, but I guess they want us to treat them like cartesian equation translations?

Am I supposed to state z=x+yi, therefore z2 would be (x-2)+yi?

Just going to bump this.

What’s the full question?

I dont understand what you’re asking

Well see how I’ve gave two answers to each of the statements/equations, the mark scheme always has the version labelled “on the mark scheme” and not the other one which is equivalent yet wrong for some reason. They’re just in different positions.

I was wondering if I DO actually have to translate the loci (like they have) instead of keeping it about the origin.


Sorry for the confusion, it’s possible that I’m just overcomplicating the question or being awkward.
