Запишите системы квадратичных неравенств, эквивалентных биквадратному неравенству:

\(\displaystyle x^4-7x^2+12\ge 0{\small.}\)

\(\displaystyle \left\{ \vphantom{\begin{aligned} 1\\[10px] 1 \end{aligned}} \right. \)	\(\displaystyle x^2\)[?|≤|≥|=|>|<][ ],
	\(\displaystyle x^2\)[?|≤|≥|=|>|<][ ]

или

\(\displaystyle \left\{ \vphantom{\begin{aligned} 1\\[10px] 1 \end{aligned}} \right. \)	\(\displaystyle x^2\)[?|≤|≥|=|>|<][ ],
	\(\displaystyle x^2\)[?|≤|≥|=|>|<][ ].
