What is the polynomial function if the zeros are -2,3,-4

For the above equation and given zeros of polynomial equation we have;

y=(x+2)(x-3)(x+4)
y=(x^2+2x-3x-6)(x+4)
y=(x^2-x-6)(x+4)
y=(x^3-x^2-6x+4x^2-4x-24)
y=x^3+3x^2-10x-24
Therefore our answer is 3

Hope this helps. Any questions please just ask. Thank you.
