Rovnica s polynomom
Rieš v \( \R \) rovnicu:
\( \normalsize\left({x^3}-x\right)\left(2{x^2}-1\right)=0 \)
\( \large K=\left\{{-1;-\frac{2}{{\sqrt2}};0;\frac{2}{\sqrt2}{{}};1}\right\} \)
\( \large K=\left\{{-1;-\frac{1}{{\sqrt2}};0;\frac{1}{\sqrt2}{{}};1}\right\} \)
\( \large K=\left\{{-1;-\frac{1}{{2}};0;\frac{1}{2}{{}};1}\right\} \)
\( \large K=\left\{{-2;-\frac{1}{{\sqrt3}};0;\frac{1}{\sqrt3}{{}};2}\right\} \)
