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

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