Řešení kvadratické nerovnice
Řeš v dané množině nerovnici:
\( 6{x^{2}} + 7 x + 2 \le 0 \) v intervalu \( \large \left( { - \infty ;- \Large \frac{1}{2}\large } \right) \)
\( \large K = \left \langle -\Large \frac{2}{3}\large ;-\Large \frac{1}{2}\large \right) \)
\( \large K = \left \langle -\Large \frac{1}{3}\large ;-\Large \frac{1}{2}\large \right) \)
\( \large K = \left \langle -\Large \frac{3}{4}\large ;-\Large \frac{1}{2}\large \right) \)
\( \large K = \left \langle -\Large \frac{5}{6}\large ;-\Large \frac{1}{2}\large \right) \)
