Given that -5 is a zero of the function $\displaystyle {f{{\left({x}\right)}}}={x}^{{3}}+{8}{x}^{{2}}+{11}{x}-{20}$, find the other zeros, and write $\displaystyle {f{{\left({x}\right)}}}$ in factored form.

The remaining zeros are: Preview Question 6 Part 1 of 2   Separate your answers with a comma.
