5) \( (x+2)^{4}-4(x+2)^{2}-5=0 \)

Use the elimination method to find all solutions of the system: \( \left\{\begin{array}{l}x^{2}-2 y=7 \\ x^{2}+5 y=14\end{array}\right. \) The two solutions of the system are: (the one with \( x<0 \) is) \( x=\square \) \( y=\square \) (the one with \( x>0 \) is) \( x=\square \) \( y=\square \)

5. Bestäm värdet på \( a \) så att olikheten \( 2 x-a<5 \) har lösningen \( x<7 \)

Find the solutions. \( \left\{\begin{array}{l}x^{2}-4 y=29 \\ x^{2}+2 y=23\end{array}\right. \) > Next Question
