Решите неравенство методом интервалов:

\(\displaystyle \left( x- \frac{1}{4} \right) \left(x-\frac{1}{9} \right) \geqslant 0{\small .}\)

\(\displaystyle x \in \left( -\infty;\frac{1}{9}\right) \cup \left( \frac{1}{4};+ \infty \right) \)
\(\displaystyle x \in \left(\frac{1}{9};\frac{1}{4}\right) \)
\(\displaystyle x \in \left( -\infty;\frac{1}{9}\right] \cup \left[ \frac{1}{4};+ \infty \right) \)
\(\displaystyle x \in \left[ \frac{1}{9};\frac{1}{4} \right] \)
