Answer :

Given that the roots of the quadratic equation are equal


Comparing with general equation, for the given equation



Hence




4p(p-6) = 0


4p = 0 or (p-6) = 0


p = 0 or p = 6


Putting p = 0 in equation given we get 6 = 0 that is not possible


Hence value of p = 6 for which the equation has equal roots.
