If the roots of `ax^(2)+bx+c=0` are `-1,-2` then `a:b:c`

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

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

If the roots of ax^(2)+b(2x+1)=0 are imaginary then roots of bx^(2)+(b-c)x=c+a-b are

Sum of the roots of ax^(2) + bx + c = 0 is..

Let a,b and c be three real and distinct numbers.If the difference of the roots of the equation ax^(2)+bx-c=0 is 1, then roots of the equation ax^(2)-ax+c=0 are always (b!=0)

Sum of the roots of bx^(2) + ax + c = 0 is

If alpha,beta are the roots of ax^(2)+bx+c=0 then those of ax^(2)+2bx+4c=0 are

If alpha, beta are the roots of ax^(2) + bx + c = 0 then the equation with roots (1)/(aalpha+b), (1)/(abeta+b) is
