A polynomial of degree 5, P(x)\displaystyle {P}{\left({x}\right)} has leading coefficient 1, and has roots of multiplicity 3 at x=0\displaystyle {x}={0}, multiplicity 1 at x=3\displaystyle {x}={3}, and multiplicity 1 at x=1\displaystyle {x}=-{1}.

Find a possible formula for P(x)\displaystyle {P}{\left({x}\right)}. You do not need to simplify your answer.

 P(x)=\displaystyle {P}{\left({x}\right)}=
