need help


plz need help ASAP on this problem
im looking for some real values (numbers) that will make this work

I've tried to make A0 an upper matrix and use -1 and -5 for the
diagonal and made A1 a lower matrix and used -3 and -6 for the
diagonal and used x=1/2 and tried some other no.# but it's not
working ........

What I'm I doing wrong

A0 is 2×2 and A1 is 2×2 such that A0 and A1 are asymptotically stable
but (1 - x) A0 + xA1 is not asymptotically stable for some x that is
between [0, 1]
