Wellllll
Keep in mind that a+b * a-b = a^2 -b^2
So you should actually multiply by
(2+4i) / (-3+2i) x (-3-2i) / (-3-2i)
And try this out!
I haven't done complex numbrs for a few weeks so I'm kinda rusty.
I'm pretty sure this should work.
I haven't tried it out but I'm reasonably sure that it should work
Update me on any progress!
