If `alpha` and `beta` are the roots of the equation `ax^2 + bx +c =0 (a != 0; a, b,c` being different), then `(1+ alpha + alpha^2) (1+ beta+ beta^2) =`

I a, b and c are not all equal and alpha and beta be the roots of the equation ax^(2) + bx + c = 0 , then value of (1 + alpha + alpha^(2)) (1 + beta + beta^(2)) is

If alpha and beta are the roots of the equation ax^2+bx+c=0 ,a ne 0,a,b,c in R then (1+alpha+alpha^2)(1+beta+beta^2) =
