Solution

This image contains a set of quadratic equations that need to be solved in two parts:

  1. Solve in K\mathbb{K}, which typically refers to real numbers (R\mathbb{R}) or complex numbers (C\mathbb{C}).
  2. Solve in R\mathbb{R}, which refers to real numbers.

I can help with solving each of these equations. Would you like to start with any specific one, or should I solve them in order?
