Rovnica s kvadratmi
Rieš v \( \R \) rovnicu:
\( \normalsize4\cdot\left(x-1\right)^2-2\cdot\left(x+2\right)^2=-2x^2+4x+11 \)
\( \large K=\left\{{\frac{{5-\sqrt{10}}}{2};\frac{{5+\sqrt{10}}}{2}}\right\} \)
\( \large K=\left\{{\frac{{5-2\sqrt{10}}}{2};\frac{{5+2\sqrt{10}}}{2}}\right\} \)
\( \large K=\left\{{\frac{{5-3\sqrt{10}}}{2};\frac{{5+3\sqrt{10}}}{2}}\right\} \)
\( \large K=\left\{{\frac{{5-2\sqrt{5}}}{2};\frac{{5+2\sqrt{5}}}{2}}\right\} \)
