-12 to get 12 at the end but I will do the problem
try x = 1
1^3 - 2*1^2 - 11*1 +12 = 1-2-11+12 = 0
so x = 1 is a root
and
(x-1) is a factor so divide and get
(x-1)(x^2 - x - 12)
(x-1)(x-4)(x+3)
so roots at
x = 1 , 4 , -3
what is the product of the rational zeros of the following function?\
f(x) =x^3 -2x^2-11x+12
