<h2>Answer:</h2>

There are more than one zero i.e. three zeros of the given polynomial.

            The zeros are:

                        x=0,-2,-3

<h2>Step-by-step explanation:</h2>

We are given a function f(x) by:

             f(x)=x^3+5x^2+6x

We know that the zeros of the function f(x) are the possible values of x at which the function is equal to zero.

Hence, when f(x)=0 we have:

x^3+5x^2+6x=0\\\\i.e.\\\\x^3+3x^2+2x^2+6x=0\\\\i.e.\\\\x^2(x+3)+2x(x+3)=0\\\\i.e.\\\\(x^2+2x)(x+3)=0\\\\x(x+2)(x+3)=0\\\\i.e.\\\\x=0\ or\ x=-2\ or\ x=-3
