The other two zeroes of the polynomial are 1 and 2.

Step-by-step explanation:

We are given the following polynomial:

p(x)=x^3-6x^2+11x-6

One of the roots of given polynomial is 3.

p(3)=(3)^3-6(3)^2+11(3)-6 = 0

We have to find the other two roots.

The polynomial can be factorized as

p(x)=x^3-6x^2+11x-6\\\\g(x) = \dfrac{x^3-6x^2+11x-6}{x-3}\\\\g(x) = x^2-3x +2\\g(x) = 0\\\Rightarrow  x^2-3x +2= 0\\\Rightarrow  x^2 - x -2x + 2 =0\\\Rightarrow x(x-1)-2(x-1)=0\\\Rightarrow  (x-1)(x-2) = 0\\\Rightarrow x = 1, x = 2

Thus, other two zeroes of the polynomial are 1 and 2.
