Answer:
[tex]y(x)=-3x(x-4)(x+5)[/tex]
Explanation: We have to factor the polynomial, that has been provided:
[tex]y(x)=-3x^3-x^2+60x\rightarrow(1)[/tex]
The factored form of the polynomial (1) is as follows:
[tex]\begin{gathered} y(x)=-3x^3-x^2+60x=-3x(x-4)(x+5) \\ \\ y(x)=-3x(x-4)(x+5) \\ \end{gathered}[/tex]
