Great video thanks a lot 🎉

I kindly request for assistance on z = 2+j hence find the value of w in the equation
Z³ - 6z² + 13z + w = 0

why do you use z? looks a lot like a 2

I agree that something else should have been used, but the way she writes z is quite clearly z, it has no resemblance of 2.

Commonly, Z is used as it represents a complex number
