is ax^2+bx+c<0 ??

both option were insuff

(1) no info about other variables
(2) no info about x

lets combine them

again there is no info of x
also b^2< 4ac
means a &c both have same signs
take simple examples
x=1 , a=c=5 , b=3 for expression ax^2+bx+c to be >0
but if x=1 , a=c= -5 , b=3 then ax^2+bx+c is <0

Ans E
