#1  no idea, since you don't show the statement below
#2 C is correct
#3 since the discriminant is negative, there are no real roots, so none of the choices is correct. Typo?
#4 I get 2.21, 0.45
That is, (4±√7)/3
Typo?
#5 Again, no real roots. Typo?
#6 A and B look the same to me, but if A is
((5√3)/2 , (5+√3)/2)
then (A) is correct.
I guess B is (5)  (√3/2),...?
