    Step-by-step explanation:

    zeroes of the polynomial = 1 & -2

    sum of it’s zeroes = 1+(-2) = -1 = -b/a…………..(1)

    product pf it’s zeroes = 1×(-2) = -2 = -c/a……(2)

    from (1) & (2) we get

    b = -1

    a = 1

    c = -2

    so polynomial = ax²+bx+c

    =1(x²) + (-1)x + (-2)

    =x²-x-2

    Hence, polynomial = x²-x-2
