Rovnica s absolútnou hodnotou
Rieš v \( \R \) rovnicu:
\( \normalsize\left|x\right|+\left|{x-2}\right|=2 \)
\( \normalsize K=K_1\mathop{\cup}K_2=\left\langle0;2\right\rangle \)
\( \normalsize K=K_1\mathop{\cup}K_2\mathop{\cup}K_3=\left\langle0;2\right\rangle \)
\( \normalsize K=K_1\mathop{\cup}K_2\mathop{\cup}K_3=\left\langle-2;2\right\rangle \)
\( \normalsize K=K_1\mathop{\cup}K_2\mathop{\cup}K_3=\left\langle0;3\right\rangle \)
