 how do i figure this out 

what represennts the zeros of the function g(x)= x 3 - 9x 2+ 2x + 48

x3-9x2+2x+48

Put x= -2

-8-9*4+2*(-2)+48= -8-36-4+48=0

Hence (x+2) is a factor of x3-9x2+2x+48

(x3-9x2+2x+48) = (x+2)(x2-11x+24)= (x+2)(x2-8x-3x+24)=(x+2)[x(x-8)-3(x-8)]

=(x+2)(x-3)(x-8)

Hence (x+2)(x-3)(x-8)=0

x+2=0 or x-3 =0 or x-8 =0

x=-2 or x =3 or x =8
