    Its really simple, just look at where it intersects. So I graphed it

    look (x−2)(x+6) -2 and +6 so it would be D

    Its a xD You have to break it down, and then find the x's

    "look (x−2)(x+6) -2 and +6 so it would be D" (ref. aloud) @Epicteatime @donnie1999 The product theorem says that if a*b=0, then a=0, or b=0, or a=0 and b=0. @aloud has correctly factored the equation as (x−2)(x+6)=0. So according to the product theorem, (x-2)=0 or (x+6)=0 Solving these equations would give x=-6, or x=2.
