Question

how what HELP

Answer 1

'write a Possible factored form'

so you don't need to write The factored form, just a possible one

Answer 2

it says 'seventh degree' so that means you'll want to write something that will have 7 terms

here could be the first 3 of the 7 for example:
(x -7)(x+5)(x+9) ..

because once our 'made up' expression is FOILed, it will be a 'seventh degree polynomial'
