I first went to the factored form of the zeroes which is (x-2)(x+1)(x+5), then i did the FOIL (first inner outer last) strategy. (If the factored form wasn’t listed, you could find it through changing the sign)
(x-2)(x+1)(x+5)
(x^2-x-2)(x+5)
x^3-x^2-2x+5x^2+5x-10
So after simplifying this, you are left with
A.) x^3+4x^2-7x-10
Hope this helps!
