Riešenie kvadratickej rovnice
Rieš v \( \mathbb{R} \) rovnicu a urob skúšku:
\( \frac{4}{2}(x-1)^{2}+(2 x-1)^{2}=4\left(\frac{x^{2}}{4}+\frac{3^{2}}{36}\right) \)
\( K=\left\{\frac{4 \pm \sqrt{5}}{5}\right\} \)
\( K=\left\{\frac{4 \pm \sqrt{6}}{5}\right\} \)
\( K=\left\{\frac{4 \pm \sqrt{6}}{4}\right\} \)
\( K=\left\{\frac{3 \pm \sqrt{6}}{5}\right\} \)
