If the roots of the equation `ax^2+bx+c=0` differ by `K` then `b^(2)-4ac=`

If one root of the equation ax^(2)+bx+c=0 is two xx the other,then b^(2):ac=?

If a+b+c=0 then roots of the equation 3ax^(2)+4bx+5c=0 are

If 'alpha and beta are roots of ax^(2)+bx+c=0 ,and roots differ by k then b^(2)-4ac=

If alpha and beta are roots of ax^(2)+bx+c=0 ,and roots differ by k then b^(2)-4ac=

If sin alpha and cos alpha are the roots of the equation ax^(2)+bx+c=0 then prove that a^(2)+2ac=b^(2)

If the roots of the equation ax^(2) + bx + c = 0 are in the ratio of 3 : 4 ,

If the roots of the equation ax^(2)+bx+c=0 are of the form (k+1)/k and (k+2)/(k+1), then (a+b+c)^(2) is equal to 2b^(2)-ac b.a62 c.b^(2)-4ac d.b^(2)-2ac

If alpha,beta are the roots of the equation ax^(2)+bx+c=0 and alpha+delta,beta+delta are the roots of the equation Ax^(2)+Bx+C=0 then prove that (b^(2)-4ac)/(a^(2))=(B^(2)-4AC)/(A^(2)) for some constant value of delta
