Answer:
[tex]f(x) = (x+ 10)(x - 2)[/tex]
Step-by-step explanation:
We want to rewrite
[tex]f(x) = {x}^{2} + 8x - 20[/tex]
in the form that would most easily help you identfiy the zeros of the function.
This the same as writing in factored form.
[tex]f(x) = {x}^{2} + 10x - 2x - 20[/tex]
Factor by grouping:
[tex]f(x) = {x}(x+ 10)- 2(x + 10)[/tex]
Factor further to get:
[tex]f(x) = (x+ 10)(x - 2)[/tex]
