The concept which I've written in highlighted middle part is of the topic complex numbers. I think it seems a little messy. I could've jumped directly into the last steps. But to make it clear about the roots of the equation x²-x+1=0, I explained the middle one. It's good if you directly remember the roots. Hoping to hear from you. Good luck and ask if you don't understand. :))

Ikr but the question is not of cbse. And the formula used in the last step is written in the middle.
