    The zeroes 2 and -2. 

    ∴ Sum of the zeroes = 2 +(-2) = 0

    ∴ Product of the zeroes = 2 × (-2) = -4 

    The required polynomial is x2 - (sum of the zeroes) x + Product of the zeroes 

    ⇒ x2 - (0) x + (-4)

    x2 - 4

    Here given zeroes of polynomial (2,-2) That means, alpha is 2 and Beta is -2 Now alpha+beta=2+(-2)=0 and alpha×beta=2×-2=-4 Then put these value in x2-(alpha+beta)x+alpha×beta x2-0x+(-4) X2+4 it is a polynomial
