so,I can't able to solve and answer

Answer 2

Answer:

hope this answer help you

Step-by-step explanation:

Given : Sum of zeroes = (∝ + β) = 0

Product of the zeroes = = -1

Required quadratic polynomial is

x2 – (∝+β)x + ∝β

= x2 – (0)x – 1

= x2 – 1

Now, find the zeroes of the above polynomial.

Let f(x) = x2 – 1

= x2 – 12

= (x – 1)(x + 1)

Substitute f(x) = 0.

either (x – 1) = 0 or (x + 1) = o

x = 1 or x = -1

1 and -1 are the zeroes of the polynomial.
