    Answer:

    f(x) = (x+ 10)(x - 2)

    Step-by-step explanation:

    We want to rewrite

    f(x) =  {x}^{2}  + 8x - 20

    in the form that would most easily help you identfiy the zeros of the function.

    This the same as writing in factored form.

    f(x) =  {x}^{2}  + 10x - 2x - 20

    Factor by grouping:

    f(x) =  {x}(x+ 10)- 2(x  + 10)

    Factor further to get:

    f(x) = (x+ 10)(x - 2)
