Bias analysis in a dual BJT circuit with feedback
The DC analysis isn't that difficult.

EDIT:  I see a far simpler analysis:

\$I_{B1} = \dfrac{V_{C1} - V_{BE2} - V_{BE1}}{R_2 + P_2}\$

\$V_{C1} = 9V - I_{C1} \cdot R_3 = 9V - \beta I_{B1} \cdot R_3\$

\$ \rightarrow I_{B1} = \dfrac{9V - V_{BE2} - V_{BE1}}{R_2 + P_2 + \beta R_3}\$

Now:

\$I_{E2} \approx \dfrac{V_{C1} - V_{BE2}}{R1}\$

\$V_{C2} = 9V - I_{C2} \cdot R_4 \$

Assume a value for the base-emitter voltages and P2 ,solve for the collector currents and check for active/saturation operation.
