I dropped 6 marks for definite and accounting for silly mistakes I would guess I got 65/75. But then it was a resit for me pretty sure I have secured an A in AS further maths
Really messed up bad. Anyone have the paper and/or unofficial answers?
Got the modulus to be 5, cause it was -5 right? So sqr. root of -5 squared gave me 5. But I probably read the question wrong considering so many are saying root 5.

It wanted the modulus and argument of z, not z^2+2z
