______(1).
Let the roots of this equation be A and B.
[A quadritic equation has two roots. Try to prove this proposition.]
Then, sum of the roots:
and product of the roots:
Thus in our case

i.e. b = -6a
and

i.e. c = -11a
Substituting these values of b & c in (1) we have

or

or
Thus the reqd. equation is
