?1(?) = 1 + 2?−1 + 3?−2 and ?2(?) = 4 + 5?−1 + 6?−2. Use MATLAB to generate a sequence ?3(?) = ?1(?)?2(?). Utilize either the multiplication property or the convolution property. send me some other proper code if anyone have

So,
x1(?) = 1 + 2?−1 + 3?−2 = 5z-2?
and x2(?) = 4 + 5?−1 + 6?−2= 11z+1?
Is that so?
then
x1=[5 -2]
x2=[11 1]
x3=conv(x1,x2)
is that what you are looking for?

no no this (1 + 2?−1 + 3?−2) is not 2z minus 1 + 3zminus 2..
here -1 and -2 are inverse power of z like below;
this is 2z raised to the power -1 + 3z raised to the power -2
