I am confused in (iia) and (iib).
If $x^4 +( \alpha  1) x^2 + \alpha + 2 = 0$ has real roots that means $y^2 + ( \alpha 1) + \alpha + 2 =0 $ should have at least one nonnegative root. This means product of roots of (2) can be greater or less than zero...But I'm not able to comment on sum of roots.
Help Please.
