If α and β are the zeros of the quadratic polynomial , from a polynomial whose zeros are .

A quadratic equation when sum and product of its zeros is given by:

, where k is a constant

Sum of the roots = = = =

Product of the roots = = =

Sum of the zeros of new eqn = = =

⇒ 2×-2× = 2-) [Using (a + b)^{2} = a^{2} + b^{2} + 2ab]

Product of the zeros of new eqn = =
