Nah it's cool I just was checking and making sure I'm being realistic with my score! Was expecting 100 UMS today but a stupid mistake like that can cost me like 10 UMS :/


Are you a Cambridge maths hopeful?

Yep, and for the z^4 equation i got that all the roots stayed the same with an extra solution, by inspection z=1 also


Are you sure it is z=1, I am almost 100% sure it was just the default equation multiplied through by z.

My calculator saved the equation, Z^3-7Z^2+11Z+123 Went to Z^4-7Z^3+11Z^2+123Z. Which can be factorized to Z(Z^3-7Z^2+11Z+123), so Z = 0, -3, 5+4j and 5-4j.

Correct me if I am wrong :smile:

It wasn't zf(z)=0.

It was zf(z)=f(z).
