### Solution:

Given that a polynomial  .
We have to find the value of   .
Let   and assume   and   to be the zeroes of the polynomial p(x), then write the sum of the zeroes.
We know the sum of zeroes of a quadratic polynomial is   and the product of zeroes is
So,

Write the product of the zeroes.

Use the sum and product of zeroes to write the value of  .

Hence, the value equal to   is  .
Therefore, option (3) is correct.
