I have resolved it by using Xcas and advice of the Xcas community :

The solution is to call the following line on Xcas :

f := det( (lambda* [ [a1,b1,c1] , [d1,e1,f1] , [g1,h1,i1] ]) +( (1-lambda) *
[ [a2,b2,c2] , [d2,e2,f2] , [g2,h2,i2] ] ) );
coeff(f,lambda,3) -> donne a_3
coeff(f,lambda,2) -> donne a_2
coeff(f,lambda,1)
coeff(f,lambda,0)

So after we can call a cubic solver to find the possible lambda root that
constraint the system.

THanks a lot for your suggestion.
Pierre.
