Пусть \(\displaystyle t=x^2.\) Запишите системы квадратичных неравенств, эквивалентных биквадратному неравенству:

\(\displaystyle (x^2+5)(x^2-6)\lt 0{\small.}\)

\(\displaystyle \left\{ \vphantom{\begin{aligned} 1\\[10px] 1 \end{aligned}} \right. \)	\(\displaystyle t\)[?|≤|≥|=|>|<][ ],
	\(\displaystyle t\)[?|≤|≥|=|>|<][ ]

или

\(\displaystyle \left\{ \vphantom{\begin{aligned} 1\\[10px] 1 \end{aligned}} \right. \)	\(\displaystyle t\)[?|≤|≥|=|>|<][ ],
	\(\displaystyle t\)[?|≤|≥|=|>|<][ ].
