19x^2+24x+1<0
solve 19x^2+24x+1=0 using quadratic formula..let the 2 roots be a and b in increasing order.

=b
=a
call the 2 roots a and b
now then this can be written as (x-a)(x-b)=0
if this product has to be not equal to 0 but less than zero,
then x should lie between a and b.,since then while one factor is positive the other would be negative and the product would be negative.
