My example is that using the quadratic I've gotten to this point z= (–2 – i ± sqrt(3))/2i. I know I need to get rid of the i in the denominator so I multiply the whole thing by i/i then I get -i + 1/2 ± (i*sqrt(3))/2. I'm wondering if I need to get rid of the negative sign in front of the i or if I'm doing something wrong, or can i just leave it as is.

Thanks
