The correct option is D 6
We know that geometrically the zero of a polynomial is a point where it cuts the x-axis. We can also find the zeros of the polynomial by equating it to zero,
On equating the polynomial to zero, we get:
(x−1)(x−2)(x−3)=0⇒x=1, x=2, x=3
Hence, the product of roots of the polynomial p(x) =1×2×3=6
