Q)

Let α and β be the roots of the quadratic equation ax2+bx+c=0. Observe the lists given below:

  List I List II

(i)

(ii)

(iii)

(iv)

 

α=β=>

α=2β=>

α=3β=>

α=β2=>

 

(A)(ac2)1/3+(a2c)1/3+b=0

(B)2b2=9ac

(C)b2=6ac

(D)3b2=16ac

(E)b2=4ac

(ac2)1/3+(a2c)1/3=b

The correct match of List-I from List - II is 

        (i)      (ii)     (iii)     (iv)

(1)    E       B       D        F

(2)    E       B       A        D

(3)    E       D       B        F

(4)    E       B       D        A
