Nech \( z_1 = x^2 + 9y\,\mathrm{i}-20\,\mathrm{i} \) a \( z_2 = 7x-12+ y^2\,\mathrm{i} \). Určte všetky \( [x;y] \in \mathbb{R}\times\mathbb{R}\), pre ktoré sa \( z_1= z_2 \).
\( [x;y]\in\left\{[3;4], [3;5], [4;4], [4;5]\right\} \)
\( [x;y]\in\left\{[4;3], [4;4], [5;3], [5;4]\right\} \)
\( [x;y]\in\left\{[-3;-4], [-3;-5], [-4;-4], [-4;-5]\right\} \)
\( [x;y]\in\left\{[-4;-3], [-4;-4], [-5;-3], [-5;-4]\right\} \)
