Answer 2

Answer:

x^3 −6x^2 +11x−6

Step-by-step explanation:

Let the zeroes of the cubic polynomial be  

α=1,β=2 and γ=3

Then, α+β+γ=1+2+3=6

αβ+βγ+γα=(1)(2)+(2)(3)+(3)(1)

=2+6+3

=11

and αβγ=(1)×(2)×3

=6

Now , required cubic polynomial

=x^3 −(α+β+γ)x^2 +(αβ+βγ+γα)x−αβγ

=x ^3 −(6)x  ^2 +(11)x−6

=x^3−6x^2 +11x−6

So, x^3 −6x^2 +11x−6 is the required cubic polynomial that satisfy the given conditions.
