a02
from the first equation? Is it unknown or parameter? Fromeq4
andeq5
follows that $a_1=0$ and $a_2=-\frac{12 \text{g2} k^2 \text{l1}^2 P}{\text{g1}}$. This can be substituted intoeq2
to yield $2 \text{g2} k^2 \text{l1}^4 Q=0$. Not sure if it is useful, but you can further analyse in the same way. $\endgroup$
