If both roots of `ax^2+bx+c=0` are the negative then

IF the roots of ax^2 +bx +c=0 are both negative and b < 0 then

If both the roots of ax^(2)+bx+c=0 are negative and b<0 then :

If the roots ax^(2)+bx+c=0 are both negative and b lt 0 , then

If the roots ax^(2)+bx+c=0 are both negative and b lt 0 , then

If the roots of ax ^2 + bx +c=0 are both positve , then

If a gt 0 and both the roots of ax^(2) + bx + c = 0 are more than 1, then

If the roots of 2x^(2) + 7x + 5 = 0 are the reciprocal roots of ax^(2) + bx + c = 0 , then a-c = "_____" .
