Below is a complex quadratic equation I think I have solved.
z2−2z+i=0 gives z=2±√4−4i2. This becomes z=1±√1−i with some basic algebra.
My question is: am I done here? In prior problems I had to evaluate expressions such as √i−1 to find it equivalent to 4√2∗cis(3π/8) and 4√2∗cis(11π/8). Hopefully this question is not as rudimentary as I suspect it to be!
