Question

z+8/z= 6x find the roots of the quadratic equation by factorisation

please help me with this​

Answer 1

Answer:

Step-by-step explanation:

z6+1=0

That lie in the top region of the plane.

We know that:

(z2+1)(z4−z2+1)=0

z=−i,i

We need to solve:

((z2)2−(z)2+1)=0

z=1±−3−−−√2

But this is incorrect. How to do this then?
