Given that one of the zeroes of the cubic polynomial $a{x}^3+b{x}^2+cx+d$  is zero, find the product of the other two zeroes.

For the given expression, ${\mathrm{ax}}^3+\mathrm{b}{\mathrm{x}}^2+\mathrm{cx}+\mathrm{d}$ 

0 is the zero of this expression implies d = 0. 

Hence, the expression can be written as: $\mathrm{x}({\mathrm{ax}}^2+\mathrm{bx}+\mathrm{c})$ 

The other two roots will be from: ${\mathrm{ax}}^2+\mathrm{bx}+\mathrm{c}$

We know that the product of the roots of the quadratic polynomial ${\mathrm{ax}}^2+\mathrm{bx}+\mathrm{c}$ is $\frac{\mathrm{c}}{\mathrm{a}}$. 

Therefore, we can say that the product of the other roots of the polynomial ${\mathrm{ax}}^3+\mathrm{b}{\mathrm{x}}^2+\mathrm{cx}+\mathrm{d}$ is $\frac{\mathrm{c}}{\mathrm{a}}$.
