Find the polynomial in X where zeros are -2, -1 and 3.

Please someone help me with this. Thanks

x= -2 , x= -1, x= 3
= (x 2)(x 1)(x-3)
then you factorise
(x�0…5 3x 2)(x-3)
x(x�0…5 3x 2) - 3(x�0…5 3x 2).

Hope you can go on from here.
polynomial is (x+2)(x+1)(x-3)

or

(x+2)(x^2 - 2x - 3)
= x^3 - 2x^2 - 3x + 2x^2 - 4x - 6
= x^3 - 7x - 6
